Wrong; you ban anyone who would disagree with your moronic claims and arguments and make you look like the ignorant asshole we know you to be. Dullards like you prefer echo chambers.
Nope, any cursory perusal of my threads indicates that a substantial number of rightwingers who can act reasonably civilized and practice a modicum of social ettiquette freely participate in my threads. I do not ban teabaggers for disagreeing. I ban them for being racists, bigots, belligerent trolls, blatant liars and libelers, misogynists, and sociopaths.
I am not obligated to provide safe harbor to sociopaths and racists and allow these subhumans to participate in civilized conversation.
