Asian here. I've actually experienced more racism from black people than white people even though whites make up the majority of the population. Back when I was a kid in school, I would be called 'Chinese boy' by black students even though I wasn't actually Chinese. The white students were polite and addressed me by name.
By your logic, if all white people are racist, then all black people are even worse racists. But let me guess, you're just going handwave my experiences away because I'm not a "real minority".
