Depends on the people/group. I've noticed that a lot of people are cool with an African Immigrant female as their "token" friend, more so than an AA one, or that in academic circles, they'll question why that black person is so smart/doing so well, and when they see their last name they're like "OH, now I get it". It's gonna be a thing if it isn't already.
So I posted proof that African Immigrants are seen in a better light and usually don't fit into the "stereotypical" mold, and you can only resort to ad hominem?
