Don't wait until a black person comes into the room before you start talking about race. Instead of attempts to have a conversation with me, we would all benefit if you held some talks with folks who look like you. Go to your neighborhood grocery store and talk to those white women who put a death grip on their purses whenever a black person passes. Or maybe talk to the scores of white men who think all black women are just yearning to sell our dignity to some red-faced Caucasian interested in living out his sexual fantasies. Instead, go to the next white person who voices such a question and ask why there's the assumption that one person can represent an entire race.
Racism is more than a couple of mean or nasty white people acting out.
If racism puts one group of people at a disadvantage, then some other group is given an advantage. On the way home, ask yourself about the many ways your skin color has made life easier for you hundreds of times over. Don't be surprised if you can't. I think not. You must also educate yourselves.
