Breh, that utopian community has never existed anywhere. Even where there aren't any racial differences people divide by nationality, even when there aren't national differences people divide by tribe, even where there aren't tribal differences people divide by skin tone or nose shape or whatever other stupid shyt they can find or they just make up gangs to divide themselves by.
My wife was born and raised in the States, but she is under no delusions about racism in the Egyptian community. I've met racist Egyptians. But her entire immediate family is cool (her sister married an Asian dude first so she kinda helped set the stage), and her cousin even went to an HBCU. The people in the family I have to deal with are chill and that's what matters to me.
And you want an interracial community that works out fairly well, try Hawaii. There are tons of mixed-race people there who are accepted alongside everyone else and White people aren't even at the top of the social structure, if anything the Asians have a slight advantage but really its pretty flat. Doesn't mean there's no racism, my best friend's parents there were racist against her dating a Black guy, but Hawaii as a community is as chill as any single-ethnic community I've ever been to and its multiethnic as hell.
