"I think it's a healthy thing in a democracy to have people disagreeing, but if you're screaming or demonizing, then the very people you want to reach -- which is those who don't agree with you -- can't hear you."
-- Bill Clinton
This is why the two sides may never come together. The Left thinks the crimes of the neocons are so incredibly horrible that they can't help but demonize, and the Right just screams the same thing over and over and over again. Neither side will ever hear the other.
