I was at, and performed in, one of the very first Tea Party events. I also performed at another shortly after the first. I attended a third shortly after. Black people were on the stage at each of the three (in particular, an elected representative, the wife of the organizer, and an MC). I guess they all hated black people.
Kristol is right: it's bullshit.
That's not to say there aren't some racist people who associate with the Tea Party. But then again, there's a bunch of liberal racists around here in Seattle (in particular, there are anti-Israeli racists, and there are racists who think that blacks are required to think a certain way or else they are "Uncle Tom").
Racists are everywhere. Yes, including in the Tea Party. But there is zero substantive evidence that racism played a significant role in the rise of the Tea Party. It's all circumstantial: it happened when a black man became President. But it would've happened if Edwards or Clinton had won the election, too. I know this because I am one of them, and I know lots of them.
