Any protest for any reason attracts extremist nuts. It seems that the only cohesive goal of the Tea Party Movement is smaller government through lower taxes and disassembling of bureaucracy. Is someone’s support of that goal tainted because Ron Paul, Lyndon LaRouche and John Birch activists show up?

Are all of the goals of the Anti-Iraq War protesters tainted because A.N.S.W.E.R., Pro-Jihad and Anti-Globalist activists show up?

If so, how can anyone publicly protest anything without getting the taint of extremism on them?
