Outside of gay people, the rest is your projection: they are homogenous society, racial problems are nonexistent. US is heavily heterogenous and despite that you segregated like a third of society at the time.
Sorry, I have lived and worked there 6 years in different cities and I do speak a fluent (though with a very heavy French accent) mandarin. It's totally not my projection but my experience first hand.
During the "diaoyu island" incident in the 2010s the sushi shop 200m near my appartment got sacked, and all japanese-brand car get smashed.
My black (and indian) friends all complained how hard they were treated. And when talking with my Chinese friends they all had very .... interesting... point of view.
Ridiculous take.
