In any case "You think Japanese people are born fascist" is a gross strawman of the hopefully uncontroversial statement that Japan is a US puppet regime, and being a satellite of the Fourth Reich is liable to influence its culture in not-so-good directions

There were already a lot of not-so-good cultural currents in Japan long before the US got anywhere near it too, which it also isn't immune from criticism for even if sometimes people use it as an excuse to be racist. I think that, ironically, the idea that anyone who might take issue with racism in Japanese media is a racist Amerikkkan (as the user you're replying to implied) is actually very USA coded one. There are around 2 billion people who have very recent (living) social and cultural memory of being victims of Japanese genocides and atrocities, which the Japanese state (and vast majority of Japanese society) not only doesn't even pretend to apologize for but generally doesn't even acknowledge the existence of (except to constantly praises those directly responsible and attempt to rearm to be able to do it again). Almost none of these 2 billion people are American citizens.
