Japanese are some of the least overt/more benign or more friendly to your face but still racist, but generally even in countries where black people are seen as "cool" like Korea and they love hip hop and black aesthetics, they are EXTREMELY racist. Fetishizing women of a race is also racist...especially because men who fetishize women's races are usually attracted to them for stereotypes and see them as bodies or traits they want in a woman and not as people.
Doesn't excuse any racism towards those groups of course. But it's just a fact, same as the fact that many black people are racist as fuck towards other minorities too, and a ton of other minorities being racist to black people as well.
Just because Asians in the US or West are relatively chill and understand beung a minority doesn't mean they won't be awful to black people in Asia where they're a majority and don't have any shared understanding of what it's like to be mistreated/unfairly judged.
