Eh, so if a "white" person is not offended, it is merely proof of their overwhelming power and domination as a group. And if they are offended, it's because they are thin-skinned racists. Good job.
Incidentally I like how you completely backed away from the African immigrants arguement. Maybe because it completely contradicts your "black people always believe and feel what I say they believe and feel, because anthropology 101". Amazing how they largely identify with cultural or ethnic norms and not with their skin colour, right. It's almost as if the "white"/"black" american racial divide wasn't a universal.
I don't think you're a troll. You probably sincerely believe what you're saying. I think you're a college kid who's never been anywhere outside of the US in his entire life. I'm also going to guess you're studying some sort of social "science" or liberal arts degree.
