I think Beck's little dog and pony show exploits some people's fear of the ethnic, cultural, and religious diversity that always existed in this country, but seemed mainly confined to the left and right coasts. Partly because of technology, ideas and cultures that were once confined to particular regions are now spreading like wildfire throughout the nation. This alarms some of the more conservative traditionalists. Obama is seen as an icon for this more enlightened cosmopolitan sensibility, and the Tea Party is a fearful reaction against it.
This may be the single most elitist, prejudiced post I have ever read on this forum. The tea party is a reaction to trillions of dollars of deficit spending that is mortgaging our children's future, government intrusion into our personal business (Obamacare) and out of control spending promoted by both political parties. But why let the truth get in the way of a good liberal chant.
Sorry, we're on to you. The tea's out of the bag!
