While I think that comment was made in jest, I think it's also important to point out that as with Muslims, there is no monolithic entity of Jewishness. Take a look at the people in the links I've been providing. The vast majority of them are Jewish, and they are fighting just as hard for the rights of Palestinians and for an end to Israeli aggression as I am, and some of them are fighting a lot harder, and making huge sacrifices.

For Jews, the consequences for doing this kind of work often includes being ostracized from family and the Jewish community, which can be an incredibly painful thing. In the Mondoweiss blog, one of the owners and contributers, Philip Weiss, was blacklisted for doing this work, and his successful career as an investigative journalist has been effectively ended.

These people deserve our gratitude and not our contempt, even if it's only in jest.
