Why doesn't the left support the Islamic dissidents?

I guess for the same reason they did not want to believe the Chinese and Soviet dissidents. It exposes their bankrupt ideology. That would mean Bush is right about the Islamists, and the left is wrong about Bush. The left is too deeply invested in their own hatred of America. When moderate Muslims look to America as a model, it confuses and frightens the left.

The left has never been reasonable in its own hatreds. Many leftists hate people who are against abortion. To despise people who believe that killing babies is wrong, is not only illogical, it is pathologically insane. Much of what the left believes is verifiably untrue. When you see lesbian protesters in San Francisco, with signs claiming that the wars in Iraq and Afghanistan are wars against people of color and you know they would be executed in either country, you have to realize these people are not playing with a full deck. They can only use the brains they've got.
