I don't presume you are racist and didn't mean to imply it. My point is that we all have inherent prejudices of one form or another. It is part of the human condition. I live in the Caribbean, where the population of the locals is probably 95% black and they have a prejudice against blacks from certain other Caribbean countries. Prejudice doesn't necessarily have anything to do with someone's skin being a different color. We all make prejudgements; some good, some bad.
I think many conservative whites (I am one) get in their own way by not recognizing when someone really is being a racist. INTENT is everything in this case, not just a word. He was hatefully lashing out at another person and trying to demean him with hateful words. Period. It doesn't matter that someone else could use the word in a different context and not cause hurt feelings. What does matter is HOW and WHY this man used the word and what he wanted to "accomplish" with his rant.
We need to be able to distinguish between true hatred and th made-up crap of Jesse Jackson and the Rev Al. When it is true racist speech, with the intent to demean another human being, we have to say "That is wrong" and bring shame on that individual.
