That's because historically caucasians have not endured the same suffering and prejudices that other races, specifically blacks, have had to endure.
So when you are prejudiced against it's a lot easier for you to "not let it get to you". For god's sake how long did white's tell these people they were less than a human being just because of the color of their skin. People tend to forget 1960 wasn't that long ago.
You taste but a TINY fraction of what others have had to go through. I usually don't get involved in these because their is no arguing with ignorance (see t00lc00l) gets you no where. I just found it quite humorous a white woman being the voice here of how to handle racism.
Again, what a stupid ****ing thread this is.
