I don't know if this story is true, since the source is extremely unreliable, but it sounds probable. It doesn't surprise me in the least. The ADL is so obsessively focused on going after conservatives, pro-lifers, and other politically incorrect groups that they often lose track of their supposed purpose, which is to expose antisemitism before it becomes dangerous.
Now Jews are faced with a new paradigm. They have not adjusted well. Some will never adjust. It would be nice to hear a sorry about that, we had it wrong from Jews to the Christian Right.
Its not necessary, but it would be nice.
