#2. "Obama is a fascist communist Nazi." Seriously? If you don't know the differences between those three ideologies, you should just leave the protest and go home. Do your homework before opening your mouth. Do not pass go; do not collect $200.
#3. The Birthers. You guys really can't come up with any more solid grounds to criticize the president? This conspiracy theory is both whacked out and out-of-date. Go away.
#4. Guns at town hall meetings. Sure, you have the constitutional right to carry them. But do you really need them at a town hall meeting with your congressman or senator? Are you expecting a war to break out? (Sadly, a war of ideas at least has broken out-- and I consider us very lucky that none of those guns were actually fired over the summer.)
#5. "You Lie!" When a US congressman feels the pressure and inclination to shout that at the President of the United States during an address to a joint session of Congress, something in the system has gone terribly wrong.
