Yep. A lot of people say a lot of things. The past is the past-- but it is really important that we all study it so that we don't have to repeat it. tl;dr it sucked and pretty much everyone did horrible stuff. Kinda makes me wary of what we're doing now that is that bad.
Do various minorities of various types and designations "deserve" some sort of assistance? I dunno. That's an ethical and psychosocial engineering question that is pretty far outside my field. Ally yourself with whoever you like! I generally do favor various types of social incentives to promote diversity and better knowledge and understanding-- but I think helping others in general is a good idea, independent of social barriers or past crimes.
Do I feel responsible for what happened before I was born? No. If people want to blame me for it, fine; that lets me know they are a dumbass that much sooner. Stupidity is one of the human universals that seems to transcend all social groups.
I do feel responsible for humans in general. We're all stuck here and should do what we can to make the world better. Sometimes that meshes with minority interest, sometimes it doesn't.
She also explains why mixed-race people are A Threat To Society.
I think being of mixed heritage is a wonderful thing-- but. I utterly loathe the concept of pride in these things. Self confidence and respect? Sure; those are good. Pride? What the hell for? Taking credit for your parents boning is absurd. Now, taking credit for being an awesome person despite whatever that you might have been through? That's great, but I've seen way too much of the former.
According to some black women, tall blonde athletic white women are The Face Of Evil Itself. 
Evil can be pretty sexy.
I'm no Christian, but, apparently, according to our black sisters, Satan Herself is a white woman.
Actually, I know some pretty entertaining Urban Fantasy / Paranormal Romance that... well, explores that. (Not the race questions, but focusing on the adventures of a female demon...) Check out Debra Dunbar's Imp series. Most entertaining.
