Meh. The idea of original or inherited sin is obnoxious, and ultimately unethical. We're here now, it is what it is--it's day one. How shall we proceed?
I'm white. I grew up in a very liberal household and have never had an unkind word for a black person. Nonetheless, I've been spit on by blacks several times, and otherwise suffered a considerable amount of personal abuse from them, some of which might have gotten me killed had I been less lucky. My response, ultimately, was to simply let it pass. And I think this is really the only answer to this--just let it go.
