There's a word for it, "agent provacateurs", Zarqawi was one, his main mission was to kill Shiites to provoke war between Sunnis and Shias, even though he was Sunni and many of his sect would suffer too. But his ultimate goal was to make things bad for us. No matter how many of his own people had to suffer.

Coulter is similar, but stupider. Without making any comment on her politics, her tactics are suicidal for her side, and especially those conservatives who are rising to her defense. Bad-mouthing 911 widows is as stupid as Jane Fonda bad-mouthing POWs, a tactic which totally discredited the anti-Vietnam War movement. If I believed the way Coulter did, I'd keep my mouth shut. That's why I wouldn't be a bit surprised if she weren't an agent provacateur for the extreme wacko left. But then again, I'm, paranoid: I see wheels within wheels everywhere.

Look up The Trust, a blackprop outfit run by the Soviet Communist Party soon after the Revolution. It allowed them to infiltrate every anti-Soviet group in the West while posing as an anti-Communist organization. And they used the cash contributions from their dupes to finance their activities.
