The average Tea Partier is sincerely against government spending - with the exception of the money spent on them.
The problem with the Tea Party is that it's been used in a way that scares people into supporting an agenda that's counter to their own interests.
At root, the Tea Party is nothing more than a them-versus-us thing.
It would be inaccurate to say the Tea Partiers are racists. What they are, in truth, are narcissists.
