You’re likely gonna experience racism in some form in any community you go to where you are the minority. People are racist, not people of some specific skin color.

So your assessment is correct, if you go to a majority black community you’re probably gonna find people racist against white people.

But when you go to the US, white is still the majority. And if you’re not the majority, you’re mostly still a large part. Statistically, the most racism you’ll experience is everyday racism, where maybe some black people believe you’re an asshole even though you aren’t. Most of the time you’re not going to experience anything.
