It is. I'll elaborate. The neonazis in France, Germany, Hungary, and other places with a growing nazi problem are calling for ethnostates. One country per ethnicity. No cultural exchange, no learning from other cultures, no exchange and most of all absolutely no exchange of people.

Now if you take the idiotic idea of "cultural appropriation" to its natural conclusion, you arrive at very nearly the same idea. Hermetically closed cultures separate from each other, no exchange. Everyone only gets to enjoy the culture they happen to be born in.

This is why it is racist. Because the separation of peoples and cultures is a racist idea.

Humanity absolutely thrives when cultures mix. The whole is so much more than the sum of its parts. Racism and bigotry cease to exist the more cultures and peoples mix. And I mean mix, not live separate lives that just happen to be in the same geographic location, just to be clear.
