Ann Coulter's words are strong. She makes her points, sometimes with a dry sarcasm or bluntness that others don't like. But she's one of the few that will stand up to the left without retreating into the PC mode that is so common among a good portion of Republicans these days. And frankly, her writings are mild compared to my thoughts concerning liberals these days.
I really don't care if some dislike her style, but trying to force distance between conservatism and Ann Coulter is a decidedly cowardly political move. PC is a compromise that is too large to accept. We need 10 more Ann Coulters IMHO.
She's writing about politics. The idea behind American politics isn't about weeding out the wishy-washy or the non-true believers. The one over-riding concept is to get as many votes as you possibly can so your guy/gal wins the election.
If Coulter is held up as a test to weed out the fence sitters or alienates moderates then she's doing conservatives harm by sending votes to the other side.
