The fact is, this thread is going to go on for hundreds of pages and regardless of any supporting historical evidence, some people are going to stick with "white people in the south created racism".
The ironic part is that by being closed minded and simply continuing to preach what was taught to you, correct or not, is the same mentality that has propelled racism into this century. I am willing to contend that most "racist" people do so because that is what they grew up knowing, and have no hard line reason for supporting it. My grand parents taught my parents, my parents taught me, and now I am going to teach my children. It is an ongoing stretch of ignorance.
