*yawns like a cat* Why are you guys so disturbed? Freedom to assemble/speech...that's somewhere in that Constitution thingy. They're saying they don't agree with Bush and that he's a crappy president. Neither of those statements I disagree with. As for 'respecting your president', our president ceased being a deity somewhere in the Nixon era, from what I understand of history, and espically during the Clinton era.
While I believe Bush won the election, and unless a rather large amount of evidence pops up otherwise, fairly this time, you can't abridge other people's freedoms and call them sick just because you dislike the fact that they're not treating the president like the hero you seem to think he is. They have a right to protest and you have the right to whine about it, for what good it does you.
