And the reason it's blowing up now is because the media monopoly is over. Back when "the media" was ABC, CBS, NBC, AP, UPI, and then-centrist New York Times and Washington Post, nobody was giving the crazies the microphone, on either side. But when Fox and talk radio came on the right, and CNN on the left (and many of the former-center media moved left), then there were people with a slant, and therefore with a motivation to make the other side look silly.

But these people (on both sides) need to reconsider what they're doing. They're making the other side look silly to the mainstream, but they're also helping the fringe of the other side recruit. That may not be a very wise policy...
