Why do Republicans & tea party folk call others fascist?

These people like calling Democrats & progressives that, yet they are the ones blatantly conspiring among each other to make the working class & poor bear the brunt of our economic recovery instead of the reckless rich who created the problem. Busting unions, closing public doors to the common people, raiding Dems homes, etc. It's such an obvious case of the pot calling the kettle black.
