No, but I admit it gets complicated. Latino pride is OK, and black pride (rather than "African-American pride) is also OK, because both terms encapsulate a series of ethnic traits, history, and NOT INSIGNIFICANTLY, struggle. "White" has none of this, so white pride is not OK.
For instance: everybody knows the first modern black American baseball player was Jackie Robinson. We are proud of his achievements as an American, and as a black American. But who was the first white American baseball player? That's not something most people know, or care about, because there was no rule restricting baseball for whites. So at least part of this discussion, and part of ethnic pride, is based on minority struggle.
