Sinji, others responded before I have and are right, you can call yourself a Tea Party Group with out being a Tea Party Group.

Also I think the problem people have is that it is a group with no national identy. You can think progressives, and the mind is filled with past and current leaders, and a charter of thier stance on everything. You can think GOP and get the same picture.
The reason it is hard todo this with the Tea Party is the fact it is a massive grass roots. The Occupy Wallstreet Movement to me is much the same. It is a new movement, it is grassroots, it have no hardcore set doctrine.

That being said, there will allways be those groups that will push social issues under the umberal of a larger movement. I have stated this before several times, and I will keep stating it. Your stance to label and demonize people is a driving force that is used by not only those on the left but on the right that wish to divide us to conquer us.
