I know I can't really talk about race because I'm white

Must admit, I'm stumped on that. Aren't white people supposedly*) the ones who are racist in the first place, and thus should be the first ones to do something about it, including talking about it? Sort of like expecting progress on women's lib if only women are entitled to hold an opinion on equality of the sexes...

*) I had a moment of enlightenment watching a japanese movie once that had some very racist depictions of indians... Oh, look, non-white racists! They exist!
