What I learned at my first protest.

People are angry.
People (media) support free speech when it agrees with their views. Check out CNN's so called interview of a man and his 2 year old at the protest in Chicago.
Older veterans are very angry at the state of our union and where it is headed.
Protesting is exciting!
Some immature people try to belittle others who do not support their views (on both sides of the issue).
People feel like they have no control.
People want to be heard.
People want to be represented.
People like my No More Pork sign best.
