There are always the bad sheep to any group.
I don't mind war protesting, if it's peaceful (the irony of that statement overwhelms me). What I dislike are the insults. Insults have no place in a protest or when trying to get a point of view across. I really don't think equating President Bush to a monkey makes a very strong political statement. I see a lot of sheep out there, on both side of the issue ("the" refering to any "pop" topic, something everyoone has heard about, and has an opinion for, but knows very little about).
What's really funny, is a general consensus among war protestors seems to be that they want Bush out of office before he does something bad. But the whole Presidential position for doing anything in Iraq is they want to get rid of Saddam before he can do anything bad.

I have my argument against using any force in Iraq right now. But it's well thought out rather than what the protesters I have had the pleasure of meeting (in life/or on the internet) use as their main reasons for protesting any war.
