I believe that the mistake observers make when looking for peak-wingnut is that they measure wingnuttery against a set of numbers. Wingnuttery can not be measured by any metric by which sane people would ordinarily measure other phenomena. I believe that we have always seen and known peak-wingnut. However, because of its size we are incapable of seeing all of it at one time. We are only permitted a glimpse of wingnuttery depending on its positioning relative to reality at any given time. This positioning simply can not be predicted or measured. In fact, it is irrelevant what position wingnuttery occupies relative to reality because wingnuttery is everywhere at all times. And it always has been.
Wingers will never be more or less sane, or more or less stupid. They will always be as bat-shit insane and pig-ignorant as they always have been. The only factor to be considered is our perception of them. It’s not that they get crazier and stupider. It’s that each time they say or do anything, we perceive them as advancing teh crazy/stupid ball one step further. This is not the case; we merely witness one more tentacle of an infinitely insanely stupid entity.
I will also shamelessly steal a term from Joe K: the Wingularity.
Someone alive today will make the last coherent wingnut argument.
This punchy term nicely captures the way that rightwing argumentation has become gradually detached from independently recognized reality and into a state of total unselfawareness. The pace of change is also accelerating. Just weeks before the election I never could guess that wingnuts would organize nationally around an act that they call teabagging. Imagine being the traveler from the future of three months hence trying to convince Americans of our semantically awkward future. How would you even start?
Thanks to the magic of talk radio and the internet, these guys can talk to no-one but each other for extremely long stretches of time, so they have no idea how crazy they sound. The time could come in the very near future when it becomes totally impossible for any ordinary person to have any idea what they are talking about. They will be beyond ordinary logic, beyond spoof. The wingularity will have arrived.
