The chances of them reading a thread and saying, "You know? That's something I agree with," are quite a bit smaller than the same person reading a thread and saying, "That's absolutely nuts! I can't associate with the party that does that," and then going on and pulling a lever for something opposite what the DUmp thread promoted.
