This is a goofy point to make. The Lnu have weapons made solely for war. You can see it during the warrior gathering: They have maces. Focus is put on the sword since it's a great symbol for the arc and the message, but realistically Thorfinn would've refused maces, battleaxes, pole-arms, and shields as well for the same reasons. The reason they don't come up is because it'd muddy the message, but part of the point is that the Lnu are also not strangers to armed conflict. There is nowhere on this earth Thorfinn can go to escape conflict.
Yes, you are correct that at the gathering of warriors from the various Lnu tribes tools that are weapons solely designed for warfare, I had been thinking primarily in the context of the Gitpi Lnu and their interactions with the Vinland settlers, so I will concede on that specific fact.
But as I also said in my post, what the Lnu own isn't really relevant to the main issue I was discussing, since as I noted the Lnu are the ones who's land is being encroached upon by foreign settlers, and in such a situation, said latter party holds the greater burden and responsibility of establishing and maintaining peaceful relations.
Also yeah, Thorfinn would (and almost certainly did) ban tools likes maces, and any axe and spear whose only utlity was for human warefare and couldn't be repurposed for use for things like chopping wood, hunting, fishing, etc (I doubt shields would be banned since its a tool who's primarily utility is for defense first and foremost). Though I doubt any of the settlers from Iceland and Greenland owned any maces and/or axes and spears designed only for warfare since as Sigured noted to his father Halfdan, Icleand had never been in any full blown war (and I am guessing that likely extended to Greenland too, since that was even less populated than Iceland). But if someone had tried to say bring a knife like the one that Thorfinn used to own (one that had no utility outside of warfare) Thorfinn would have defnitely prohibited that from being brought as well.
And yes, I know there is nowhere on earth Thorfinn can go to escape conflict, the author and narrative itself is intensely aware of that, but the other main point of the narrative is that despite that tragic fact, people should still try and escape from and minimize conflict regardless. That the very pursuit of the impossible ideal is the right and ethical thing to do.
I'm not actually sure about this. Ga'aoqi is essentially the (much more competent) Lnu counterpart of Ivar. Ivar has a sword because he's a bellicose dumbass, not the other way around. Similarly, Ga'aoqi's interest in raiding precedes the sword because he is a warrior and a raider. The sword just gives him an explicit narrative goal beyond "kill them and steal their shit." Either way, it's pretty explicit that the gathered warriors were going to raid one way or another because, well, they're already here and they're fighters. We've already seen this with how the Jomsvikings dissolved - even after being disbanded the warriors fought because they were there, fighting is what they do, and they had nothing else to do.
Anyway, I've been looking at comments on here and other sites and I think people are too harsh on Ivar and others are too harsh on Thorfinn. Thorfinn is trying to do something that, in his era and from his perspective, has never been attempted before. Ivar's an idiot, but he's well intentioned (in regards to his own people, anyway) and some of his points are good ones: Trade and relations alone cannot stave off conflict. He and the other settlers are from a culture where blood feuds and wars between intermarried families are well-known and not that uncommon, so it's not like Thorfinn's idea is a silver bullet.
My take on the sword is that it's entirely a symbol in this arc so every argument about "Well, if the literal item wasn't here then things would be a bit different!" is missing the point. If Ivar had hacked Miskwekepu'j's hand off with an axe then the same tensions would've popped up. The sword had no chance of not showing up because it's not really a sword, it's a representation of the desire for battle itself. That's why with the Norse on the back foot, the sword is now in Ga'aoqi's hands.
First off, we don't know whether Ga'aoqi regularly participated in raids on other Lnu tribes before, him being a warrior brute with a lust for power and violence doesn't guarantee that he actually was able act on said impulses regularly. And considering that the other Lnu tribes we've are all ones who live on the island, and there was no indication that the island tribes were in regular and frequent deadly conflicts with each other, that's evidence to suggest that raiding wasn't something super common among the Lnu of the island.
Furthermore, the Jomsvikings weren't risking the threat of exposure to an epidemic when they fought among themselves after they dissolved. Ga'aoqi's peers even noted that they were taking a risk by going on a raid, so I'd say that's even further evidence that if Ga'aoqi's primary motivation hadn't existed the likelhood of him and his peers iniating a raid would have indeed been smaller. Again that's not a gaurantee a raid wouldn't have happened, but I think it is foolish to try and claim that the chances wouldn't have been reduced if Ivar and his sword hadn't been an issue.
Also, as I have previously stated, I am not saying the sword by itself is sole difference maker, I have repeatedly argued that it was the sword AND Ivar together that made a meaningful difference. Also if Ivar had used a tool other than a sword to hack off the shaman's hand, the meaning and impact while still significant ,wouldn't have necessarily been quite as striking since a sword is an entirely new tool the Lnu (the best way they can describe it is as a "big knife"), while a steel axe wouldn't just have been viewed as a superior version of a tool the Lnu already own and use, and wasn't something the Vinland settlers would have brought with them for the sole purpose of harming other humans.
Most people started Vinland Saga because they've heard it was a cool revenge story, even if some themes were indeed present at the start, they weren't exactly the focus and most people were probably not watching/reading this work for those.
The anime also reflect that, the first season received unanimous praise while the second was divisive and an eventual third season will probably be even more so.
My take on that point would be an issue of marketing and what expectations a reader may have.
Those themes were most certainly the focus in the first arc, they were just presented in a different manner. And said first arc never really presented itself as some "cool revenge" story, it was always explicilty portraying it as a harrowing narrative for Thorfinn and the other characters. If readers/watchers couldn't tell from the first season that the narrative was always fundamentally built on the tragedy and condemnation of violent human conflict, that's their issue with their ability as a reader/viewer, not with however the series marketed itself (like the later arc of Vinland Saga only work in part because the first arc focused on how Thorfinn was originally living a life of violence in pursuit of revenge).
That's the issue I have, it IS hypocritical because you ultimately don't kill with symbolism but with whatever is safest and/or deadliest and a crossbow is both safer and deadlier than a sword hence why it should also have been banned. If Hild wants to hunt, she canuse a bow instead.
But Thorfinn's ban wasn't based on what and/or how someone can kill another person (and/or how safe and/or deadly that method may be), Thorfinn's ban was based on the message it sends to bring a tool solely/primarily designed for harming other people under the context of them as foreign settlers who are traveling to another land, inhabited by native peoples already living there, with the intention of settling and developing said inhabited land (and are well aware of how things like a language barrier will pose a challenge to relations). And Hild herself has stated that the primary function of her crossbow is for hunting, the fact that it has the capacity to be easier and more effectively deadly than other tools solely designed for warefare (like swords) is not what Thorfinn was not the factor Thorfinn formulated the reasoning behind his ban, and thus that's why it is not hypocritical.
It's like how if someone built a house next door to you and when they move in you see them bringing with them a collection of nasty looking daggers whose only use is for harming other people and they are regularly carrying them around on their person (and you know that they aren't an antique seller), the vast majority of people will react more viscerally to that than if you simply saw someone moving with a hunting rifle (and you knew that they were a hunter), despite the latter tool having a greater capacity for being deadly.
But they don't know that because the germ theory hasn't been discovered yet, they knew that being near someone ill or touching an object that was used by someone ill can transmit a disease but they didn't know why.
They don't need to know about germ theory to come to the assumption and limited understanding that directly interacting with a person is a greater risk for exposure than if they just interacted with objects a sick and/or potentially infectious person had come into contact with, like even some animals will intuit that. But again, this is largely off topic from the main point being discussed, so there really isn't much point in discussing it further.
But I did agree that the shaman and Ivar accelerated the process of conflict... Why are we arguing on that point again?
I don't know, all I know is that my argument has always been that Ivar and his sword contributed meaningfully to how things went to shit and thus hold some degree of responsibility, even if they weren't the primary main factors. I think if Ivar and his sword hadn't existed the degree of how bad things turned could have been potentially lessened, but I have never tried to claim that nothing would have gone to shit (if Ivar and his sword hadn't existed). I think the narrative is pretty clear on that as well.
I wouldn't discard the most popular opinions because it ultimately show how something is perceived by most and/or how good the author is at conveying something to a large audience.
I don't think it can be said that the opinion that "Ivar and his sword hold the entirety/majority of blame for everything going to shit" is the most popular opinion. And even in cases where a a work has mass misconceptions about it, that doesn't automatically speak to and/or indicate the quality and effectiveness of the storytelling. For example, the novel Lolita has tons of inaccurate opinions about it, that doesn't mean Vladimir Nabokov poorly wrote his novel or was trying make people sympathetic to pedophilia and pedophiles.
So again, I will say it is not really relevant to the issues I am trying to discuss.
