I'd recommend to the OP that you get off the internet, go out into the world and actually meet people that are from more historically disadvantaged groups than you. It really only takes a minimal amount of life experience to realize that all of us have an obligation to rally behind people who have gotten **** on all of their life just because of the circumstances of their birth.
While I think it's great that people want to rally behind others, I disagree that anyone has an obligation to. We're still animals at heart after all, and the world is survival of the fittest. It's a great mindset to help the disadvantaged, but when we treat it like an obligation it really takes away from the spirit of the whole idea IMO.
