Why do libs bother posting on this site?

Listen, you're never going to convert the tea party people, you're not going to sell them the idea that universal health care would work better than our current system, you're not going to talk certain people out of relying on the Bible for their daily guidance, you're not going to convince them that ity is anything but a sin, and you're not going to convince them that Bush was bad for this country. Why don't you just give up, and go back to Democratic Underground or listen to Bill Maher instead. You're wasting your time here!
