From somebody who is a Liberal and against the war, this is my summary of the Bush Administration's action followed by the protesters (especially those in San Francisco):
An act of sheer idiocy was responded to with another act of sheer idiocy.
These moron "protesters" are doing untold harm to the very issue they are supposedly backing. There is little more that they could do to discredit themselves and by extention the issue the claim to support.
Baka.
