Hi, There was a lot of post's I don't have time to read.. but when I saw the topic title was about whites addressing racism, i automatically thought of Tim Wise. He's a white male who addresses topics of racism, and is considered a racist by a lot of white people. I think he makes a lot of really good valid points.. you should check out his articles...
