You know something. I don't buy into it. Sure, there are tea party types who are racist. But it's more that white supremacist are linking themselves to Tea Party types, then the other way around. White supremacist groups are parasites that will try to attach themselves to anything.
I do think these Tea Party types are full of shit. Like I have said many types, beware of any group that cries "freedom", "1st amendment", "patriot", etc. They are the first ones who want to remove those things from anyone who disagrees with them.
