You're making quite a lot of assumptions about my experience, none of which is really correct. I wasn't openly hostile to these "antebellum plantation families", but I avoided them as much as possible. Most of my friends were from other liberal-leaning families.

Many of the people I spent time with were poor whites. I wasn't ever beat up by a poor white kid, and I wasn't afraid of any black kids. If I consider the political leanings of the white kids I knew, I didn't notice much difference in prejudice based on social class. So again, denying my experience just because you're mad (I assume?) that your segment of society is being painted with a certain brush. And imagining all sorts of things about my life to dismiss my attitude to boot.

Is what I wrote earlier unfair to you? Yes, probably (so are your replies to me). But I'm not talking about you. I'm talking about what I experienced, and that crosses boundaries of social class, despite your implication that it doesn't.
