Cocaine? Meth? Marijuana? Thorazine? Or is Janeane Garofalo just weird?

What is wrong with Garofalo in a new Fox video in which a reporter challenges her characterization of Tea Party protesters as racists?

Why does she go up to the camera lens and come close to pressing her nose against it?

To recap, the left-wing Garofalo previously said of the anti-Big Government protesters:

This is about hating a black man in the White House. This is racism straight up. That is nothing but a bunch of teabagging rednecks. And there is no way around that. And you know, you can tell these type of right wingers anything and they’ll believe it, except the truth. You tell them the truth and they become — it’s like showing Frankenstein’s monster fire. They become confused, and angry and highly volatile. That guy, causing them feelings they don’t know, because their limbic brain, we’ve discussed this before, the limbic brain inside a right-winger or Republican or conservative or your average white power activist, the limbic brain is much larger in their head space than in a reasonable person, and it’s pushing against the frontal lobe. So their synapses are misfiring.

Garofalo seems to know a lot about psychopathology. I wonder why.
