When I lived in SoCal I dated a chick who was originally from the Bay Area. We were cruising down I-5 and she was giving me a ration of **** about being from the South, and how that meant that I was a racist. Just then she got cut off by a Mexican guy in a ricer and she began screaming (she suffered from severe road rage), "You 17ing beaner!". I just looked at her and said, "And I'm the racist one here..." She never brought the subject up again. edit to add sidenote: She was a direct descendant of Confederate General Braxton Bragg...
Second anecdote: When I was in the Navy one of my buddies was a black guy from Memphis. He met his wife when he was stationed at Bayonne, NJ, and she was from Boston. He told me that when they got married, she couldn't understand why many of his friends were white guys from the South. He told her that she'd figure it out when they got stationed in the South, but that he never knew where he stood with Northern whites or blacks. Further, he <span style="font-style: italic;">did</span> with Southern whites and blacks, and that if you liked each other that was it, there was no fake friendship or treatment based on race. He noted that it was a helluva thing to be discriminated against by New England blacks because he was from the South...
