Eleanor Cliff-jumper, Terry McAwful, and Susan Ostrich do it for me, along with everyone on your list. It's a combination of smug condescension and insipid lack of minimal self-awareness and self-criticism that do it to me.... also, suffering with a face and voice like those of Eleanor Clift really do make me want to end it all immediately..... :^)
McAwful definitely has to be on the top of anyone's list. In his case, the dishonesty is there, and the relentless moral imbecility. I also find his voice monstrous. Above all the falseness of his smile smile.
