We need more "I call bullshit" from the left directed on those towards the right. Countering BS with more BS won't get anything accomplished. All it does is create uninformed lemmings on both sides.
What the left needs to do is put the facts out there in a clear, concise form (I think this has been Obama's biggest failure btw), and let the public decide for themselves. If there's one thing the right is really good at, it's finding their message and sticking to it (ex: "we need to stop the gravy train"). Keep hammering the facts home, and eventually they will sink in.
