Glenn Reynolds very eloquently replies in this post:
When Ted Kennedy can make an absurd and borderline-traitorous speech on the war, when Michael Moore shares a VIP box with the last Democratic President but one, when Barbara Boxer endorses a Democratic consultant/blogger whose view of American casualties in Iraq is "screw 'em," well, this is the authentic face of the Left. Or what remains of it.
There was a time when the Left opposed fascism and supported democracy, when it wasn't a seething-yet-shrinking mass of self-hatred and idiocy. That day is long past, and the moral and intellectual decay of the Left is far gone.
What is most shocking to me is the moral depravity on the Left. I know many Leftists at my university who'll brazenly compare the American soldiers to the SS but say that Stalin has been improperly demonized. Practically ever single time they refer to democracy in the US or in Afghanistan it's like this: "democracy".
Once a friend told me that George W. Bush looks eeevil and that Saddam is a bad guy based on what I had told him. I was left speechless.
The Left today is de-facto pro-Islamist.
