Let them protest. Its my experience that these people are just preaching to thier particular chior. Their methods usually end up turning off those that they are trying to influence, namely those that are on the fence or have views that differ from thier own.

You will see lots of those espousing socialism and communism. You will see them comparing Bush to Hitler and the Nazis. You will see them saying he lied. You will see them saying America is bad. They will be violent , they will be vulgar, they will be irrelevant.
