Apparently, that is the new (old) strategy for MoveOn.org. When the Anti-Defamation League catches them with profoundly anti-Semitic comments on their site and sends a letter objecting, they try to blame those evil conservatives.
Perhaps a name change for the group is in order. How about GrowUp? The "it wasn't me it was somebody who just ran by and did it" defense is so second grade.
On any given day, on any given comment thread on the major lefty sites you can find steaming heaps of anti-Semitism and hate. This is not some unidentified "conservative" bogyman. This is the people who flock to those sites. It is about time for the Democrats to realize exactly what they are getting into by pandering to the left. At some point, the rabid hatred of Jews and Israel will start costing Jewish votes. That could well be fatal for the party.
