Instead, you came at it from "Whoa boy, this guys crazy, he thinks Obama and Co are really going to kill him, people must be crazy to actually listen to this guy (based off the notion he's paranoid)". This immediately invites people into the thread simply to bash, trash, and bag on Beck and his viewers, even the more rational ones that don't take the hyperbole as serious suggestions like some of the fringe do or doesn't believe everything he says is gospel. This immediately moves the conversation AWAY from warning people "how off base" he is because YOU are then seeming offbase yourself in actually believing something like this is meant LITERALLY. If your TRUE intention was REALLY about convincing people he's off base you'd be focusing on people that are viewers of Beck, at least casually, and could be swayed. Those people aren't the ones likely to think "OMG He really thinks Obama is going to try to kill him!" because that's absolutely a silly and ridiculous notion to believe unless you're someone thats only real experience with Beck is Media Matters, blogs, YouTube clips, or internet forums
