This whole argument just comes down to the context of the word racism. Paul is right when he follows his context of the word- the dictionary definition. Likewise, all of his opposition is right when racism is looked at in a realistic point of view as a facet of power.
Therefore both sides are correct- its just depends on the context.....
Today I was standing in line to get a soda, a woman looked in my direction and asked for some change. I asked her if she was talking to me and she said no- I smiled at her and said okay sorry. When I turned around her boy friend got in my face and said "damn right she wasn't talking to you cracker". I don't know if that is racism or bigotry; whatever you want to call it, it was wrong
Whether or not Paul is right, in his meaning of racism, I think this is what he is refering to as there being "black racism"-
