So quick to be a radicalist. I've never used TikTok a day in my life, but since you don't like my truth, I must be one of "them", huh? Them scary TikTok watchers? And then deliberately twist my word as racist? Are these women not Japanese? If the cavegirl Tiari isn't Japanese unlike these girls, then why wouldn't I refer to them as "Japanese women"? You could have intepreted it simply as that - a concise way to refer to the different subjects in discussion - but instead you chose the radicalized version of understanding.
Also, how did you miss the fact that everything I said was contained within the context of the story? It's literally in the first sentence "This is the start of the civilization". Did I say anything about women nowadays should fight? No, I said they should fight there - in this story, at that pivotal moment in history - and even so, arm-in-arm against the Neanderthal enemy, not against their own tribesmen. To put simply, if you want power and position in that dark age, you fight for it. Taiga did. He was initially perceived as weak, thin and naive by the tribe - no different than a woman's physique perceived by a man. Taiga dove in, braved the very real mortal danger, and earned his position. These women can too. They are modern people, they know how to even the playing field. They know there's no need to rely on raw physical strength, unlike the cavemen.
All in all, the narratives you're constantly exposed to become your version of normality. The fact that absolutely no one noticed this opportunity for women, the fact that some easily found a reason to justify these girl's inactions, shows that this image of passivity, non-violence, non-aggresive and submissiveness has become their norm of women. They see that and think it's seems right without any issue whatsoever. Why is it that in a world of absolute violence, aggression and constant killing such as this, you don't see these characters and ever question yourself "huh, how do these delicate snowflakes make sense here?" Trust me, if Taiga acted like that, everyone and their grandpas would've squirmed and called foul a hundred million chapters ago. So, make more stories to normalize a more equal position and strength for women. And while they're still not made, I'll have to resort to reminding people that an alternative version of their favorite patriarchal story could logically exist too.
This is my way of keeping young readers from mistakenly thinking these inherently skewed depictions are logical, acceptable or justifiable.
