Tim,
I am not nearly as annoyed by John's self-flagellation as you seem to be. I regard our friend as a sort of obtuse curiosity - a conversation piece, giving the same impression as would an enormous ceramic penis on a pedestal in the Louvre. How did it find a place here? Is it art? If so, would it not be better to display it in a place more appropriate?
The primary allure of John's madness is not shock value - although I once threatened to fly to Indiana and kick his ass if he did not apologize to one of our mutual friends. We read him for the same reason Bill Griffith was so successful with Zippy the Pinhead comics: Hidden within the nonsense is an encoded message. The message might be abhorrent, it might be insightful and it might be just plain nasty, but it is difficult to resist the temptation to decode the residue that erupts from the airless bowels of his violently conflicted, painful, guilt-riddled, self inflicted insanity.
The contradiction between his internet persona and the skinny-legged pot belly who carries his bag, replaces every single divot and fixes every ball mark on the green - not so much as a matter of habit, but an OCD condition - is striking until you look closer. Barny lamented to me once that he was jealous of my freedom living in San Francisco - opining that in his life back home, nobody could possibly grasp the concept of this board let alone the vectorous nature of his posts.
If left to his own devices - assuming his extremely attractive wife could be locked into a state of suspended animation for a year or so - it would not surprise me to see him naked on roller skates, smoking a joint with 100,000 other people at Bay to Breakers. John's biggest problem is that he's a closet crackerbox - emotionally locked in the town stocks - fearful that his peers in the narrow-minded prison of his stomping grounds will someday discover that he is not a boilerplate, pro forma idiot like the rest of them.
"The down side of Americans being obsessed with pop culture is that they kind of like it light."
