Whatever she's done, it still speaks volumes about you that you chose to call her a 'disease'. Why didn't you just leave her quote at that? You would have come off as far more objective.
It seems to me that you are criticising Ms. Palin for something that you indulge in yourself. Isn't there a word for this behaviour?
Hey! Ben!... over here. I called her a disease.... because I think she's a disease. I don't see why the convo has to go any further because you aren't addressing the racially charged part of this at all, you're just, defending Palin for some reason? Right-o! Good day.
