I have to say I'm very dismayed with the CJC's opposition to allowing George Galloway speak - especially since Bernie Farber initially said he supported his right to speak, then changed his mind. And contrary to what a lot of people think here, the CJC has been a progressive organization, in the areas of human rights and poverty. In the 1990s they led the fight against extreme right groups. They were very supportive of gay rights long before it was popular. But it seems to be lining up more and more with the agenda of the Jewish right (keeping out Galloway, doing nothing about the JDL) - who I don't think represent the community mainstream.
Bnai Brith also used to be progressive - I remember a time when you could find a lot of NDPers in Bnai Brith lodges - but it's now on the far right. But they are no longer a significant force.

I say this with dismay because I don't think this behaviour is congruent with the progressive community I grew up with. I'm not talking about Israel's right to exist or Zionism or anything of that nature. I don't think my views are out of the mainstream.
