It is with full knowledge that I have a peculiar skill lacking in many progressives that I frequently listen to spacey right-wing radio talkers. I never feel changed by it, a bit irritated at times, but not changed. I find it interesting to find out what the other side is thinking (or being told to think). Now that Limbaugh is the defacto head of the GOP it is imperative that at least a portion of progressives are listing in on the lunacy. Why should we be caught by surprise by whatever dung Rush and the army of Rush wannabees are spreading over the public airwaves?
Way back, when he started going national, Rush took many more phone calls from listeners. Invariably, every call started this way, "Hi Rush, I agree with everything you say." Rush, having slightly more intellect than his callers would sometimes stutter over this. Eventually he started correcting the listeners and admonishing them to say "Ditto" instead. He told them that this was just to save time, but there were a couple of instances early on when he admonished people that they couldn't possibly be a thinking human being and agree with everything another person said, but eventually the time saving argument won out. They callers couldn't quite grasp the more nuanced explanation.
Over time Rush redefined the whole "Ditto" thing as a sign that the caller was a high-minded patriotic American. So the typical Rush listener hardly noticed as Rush very slickly moved his callers to an expression he preferred and then adjusted that expression to gloss over its original intent. What was created to cover the dull minds of his listeners became the proud calling card of his uber-patriotic drones. The truth is they still agree with everything he says, even before he says it. It takes real intellect to form your own ideas.
