We'll never get there by saying "we're not there yet, so it's fine to discriminate on race/culture/nationality under _our_ terms, because we're doing it for the right reasons".

The whole concept of calling people wrong for cultural appropriation, for example, it's just racism. If you want to keep racism, then keep doing that.

Same here: "you don't have the right ancestry so you can't do this". It's racism. We can keep it; I'd rather not.
