Here's a video of Bernie Sanders "debating" Michelle Bachmann, which provides a truly outstanding example of what happens when someone tries to reason with right wingers. It is really painful to see, so I don't expect anyone to watch it all (I couldn't take it) but take a look at a little of it, because it is such a great example of the techniques which Republicans use to prevent any kind of meaningful, fact-based conversation from taking place. I first noticed this on talk radio in the late 1960's, and I have seen it ever since. Anyone who thinks this pathetic behavior is the result of stupidity or ignorance on Republicans' part is deeply mistaken. It is a systematic behavior which can be seen again and again, ad nauseum.
So, here is the strategy:
1. As soon as you get hold of the microphone, rattle off as many lying Republican talking points as possible, harshly criticizing your opponent as a boor if they dare to say anything while you are talking. This way, no meaningful rebuttal can hope to cover more than a fraction of your distortions, leaving the others untouched.
2. Whenever they have a chance to say something, continuously talk over them, no matter what they say or do, totally ignoring your synthetic outrage of a few seconds ago whenever they tried to correct you.
3. After your orgy of lies, be sure to find a way to accuse your opponent of being a liar: Michelle Bachmann in this case to Bernie Sanders: "'You Shouldn't Be Lying." This strategy is designed, on the rare occasion that a Democrat would be unpolite enough to point out the truth about Republican talking points, to be sure that all many people will take away from the conversation is that both people accused the other of lying, and they probably both were.
As I said above, I have watched this systematic behavior for decades. It is nothing but a way of shouting down all opposition and silencing the truth. Of course a closet right winger like Wolf Blitzer* will play right along with it and pretend that it's just a fine way to deal with our national problems.
*Little known fun fact: Wolf Blitzer started his career in broadcast journalism working for Pat Robertson at the Christian Broadcasting Network.
