People are like "Ew that's a child you sickos!" but like, bruh - Look at that thing. There is nothing human about those proportions. This isn't a human child. It's some kind of hideous changeling, a humanoid abomination from beyond the stars sent to infiltrate our world, subvert our governments, and presumably steal all our brains to be put in jars for further study. The fact that it doesn't reflexively trigger the uncanny valley response is horrific in and of itself. It's already overcome our instinctual defense against infiltration. It's already in our homes and the halls of government. It's already won.
(I know the lizard people from space control our government thing is a white supremacist dog whistle for Jewish people. I actually spent a lot of time thinking about whether or not to post this because the whole genre of "Alien infiltrators" stories is so tied up in white supremacy, anti-communism, anti-immigration, racism, and so forth. But, eh. Dumb jokes about Genshin probably aren't harmful? But feel free to call me out if you think I should take it down or that there's aspects I'm missing.)
As long as you're aware its a dumb joke then really nobody actually cares, its words into the void.
Now for the people that actually want to once again use "return to the glorious days of 1985" as the basis of their anti-anime perpetual struggle session I say good luck with that. Complaining about anime proportions is often an entrance into discussing pedo shit, which is fine and a good discussion to have for those that are not familiar with these issues. But otherwise don't make the mistake of thinking this is anything but a fringe opinion.
You can have modern anime without pedo shit, in fact most of the industry is about as mild as the rest of western media. Most people are in fact not pedos, please don't make the mistake of labeling an entire country as full of pedos, it is all realy, realy cringe coming from westerners.
The problem, and yes its a real problem, is that the pedo and outrageous shit gets way too much visibility making it seem much more main stream than it is.
Once again reminds me of that phd paper or whatever of the researcher thinking the recent uptick is because of Japanese "culture". Like open a damn history book etc etc.
