Little Theeedeee's ancestors were just as big of racists as mine were.
This is something he hates to admit so instead of facing up to this, he simply transfers his racist legacy onto the south and all southerners.
His bravado about wiping out the southerners in an act of genocide only confirms him as a little piss ant coward who yearns for social acceptance in a PC circle he runs within and it at the same time makes him feel vindicated and given absolution over his own family tree that quite possibly contained slavers.
This PC attitude is not uncommon among the theedees of modern society and it only gives him a false sense of moral superiority over those who are the racists scapegoats of modern times, the southerners.
