Not really from what I observed.

There are many fractions in so-called tea-party movement.  Like any movements, there are certainly some bad apples. From what I observed, the main stream of this movement is “against government and establishment” rather than “against certain group of people”. For example, they put their candidates to challenge GOP establishment candidates in the primary races.  They are frustrated with out-sourcing, growing spending, deficits and debts.
