I think this is too simplistic. The US is a country of some 320 million people and the experience of racism undoubtedly varies enormously across cities and states. A blanket statement like this can't convey the complexity of the situation.

I live in the UK, where we've seen a horrible rise in racism after the EU referendum. But what country in the EU can honestly say they don't have serious problems with racism in their society?

Across EU nations, there are many racist political parties, not at the fringes, but actively shaping and influencing political discourse.

I really don't think we in Europe are in a superior position when it comes to issues of racism. In fact, I'd argue we're probably less likely to acknowledge or consider it a problem.
