Yep. Actually a very large portion of the left is virulently anti-Semitic. Just take a gander at some of the posters at DU and Daily Kos.
Some are more anti-semitic than they are anti-Christian.
What they have in common is that they hate the Judaeo-Christian value system that our country is based on, because the lot of them are a bunch of kooks and misfits that will LOSE if made to play by the rules inherent in our culture.
