You literally have people saying Mass-Immigration is needed cause "we need the influx of ideas and creative geniuses". Elon Musk literally used Nikolai Tesla as an example of an immigrant who revolutionized industry and technology to justify his pro-H-1B Visas stance - "hence we need mass immigration likes a giant fishing net to troll the next genius".
Pro-Mass-Immigration People literally say we need mass-immigration to prevent the catastrophe of population-collapse from dwindling birth-rates and to have workers to support /save/care-for the next retired generation.
FFS. You can argue that the impending meteor the humans couldn't see that the aliens "prevented" is a metaphor of the impending population-collapse of 1st-world nations (Japan especially) that the influx of mass-immigrants will "prevent". The two main-protagonists questioning the validity of the meteor can be seen as questioning the need for mass-immigration to prevent population-collapse; instead of making solutions for native-birth rates.
You can argue that the special 1st-class treatment and 2-Tier Law-System the Aliens enjoy are like the mass-amounts of Muslim immigrants in Europe - especially in Britian where the British Law-System has been covering up the Pakastani/Muslim British-Child Rape Gangs at worst and at best giving them slaps-on-the-wrist punishments (just today a young British man was given 4yrs in prison for "inciteful online-posts" while a convicted Muslim Rape-Gang Leader was given only 3yrs).
Nothing that you invoked is even remotely related to the contents of this manga thus far. Not a single rhetoric you invoked is invoked by the manga at hand. You just thought this was an opportunity to mag dump your accumulated talking points at me for several paragraphs, loosely pretending that they have anything to do with the actual manga.
"The meteor (real or imagined) that the aliens may or may not have saved the Earth from is a metaphor for population collapse, even though the aliens brought along with them advanced tech and industry, and even though the aliens do not settle on Earth as a solution to the catastrophe they already averted."
"The aliens represent Muslim immigrants in Europe, despite the fact that their celebrity and privilege is specifically because they ostensibly saved the Earth from annihilation
and brought superior tech and industry." No, Nikolai Tesla is not "mass immigration", nor did he immigrate to the States on account of mass immigration, nor is this manga's premise (having been shaped potentially months prior to its release) taking into account Musk's comments that substantially postdate even the beginning of its serialization.
The most egregious argument you try to make is that questioning the
existence of the meteor and its ensuing crisis is supposed to, in any way, correspond to a questioning of the need for mass immigration instead of increasing native birthrates. It would have been marginally more sensible if you tried to correspond it to the questioning of the existence of the problem of the birthrate crisis.
I'm sorry you're too smug and tunnel-visioned to see multiple interpretations of this manga - even when there are mass amounts of readers saying they see the Anti-Immigration Interpretation of this and other readers on the other side of the coin saying this manga is "racist/xenophobic/etc." garbage for its Anti-Immigration symbolism.
Yes, because you're all politically brainrotted. Most of you don't even touch the material you choose to talk about and just synthesize a meager understanding based off what other people (who may or may not have consumed the material) say. Most of the people who do talk about it are more interested in making it a culture war bludgeon than ingesting the narrative as it is. Left-wingers do the same exact shit with Persona 4-- either coercing it into their alleged political worldviews or condemning it for appearing to suddenly cease to fit into their preconceived notions even though the characters will telegraph and then dictate their character arcs in full, nearly facing the player as they speak, with all the subtlety of a Saturday morning cartoon.
It doesn't even have to be the product of political brainrot. The Evangelion fanbase argues about how justified Shinji Ikari is for being a coward, when the guy jumped in a volcano with his EVA of his own free will, overall wants to pilot EVA so he can have a place among other people, and only ever briefly quit whenever he was told he wasn't needed-- not when he got too scared. They probably still call it a "deconstruction" of the mecha genre even though the only mech is Jet Alone and the EVAs and Angels are both
kaiju. People think Naruto is principally about (or was supposed to be about) an untalented flunky becoming the strongest through hard work, even though the entire first chapter has him establishing that he wants to become the Hokage so that people will acknowledge him, the chapter crescendo being Iruka acknowledging him despite the loss of his (Iruka's) parents at the hand of the monster sealed inside Naruto.
I can go on and on about how masses of people are somehow capable of altogether missing the basic and most critical points of stories, even when they're spelt out in 72pt text. Don't refer to the masses having nary a practical understanding of what mass immigration looks like in order to legitimize your absurd and obviously ill-fitting fixation. Your position doesn't have more legitimacy just because you can say you're a part of a misled conversation.
