Funny how ones personal bias colors their perceptions. I often am saddened by those who generalize by lumping all Obama followers, gun owners, welfare recipients, Mexicans, etc. into one pot. I do not believe broad brushed generalizations are the sole domain of any given political group, until you hit the far fringes. Then you get skinheads, KKK and such who hate all Jews, blacks, the educated, etc.
The Tea party has many fine folks, and some good ideas, but like any new group tends to attract haters and full on nut jobs too. If they aren’t vigilant to keep the nutcases out it will hurt them badly next fall.
