"I'm six foot five, weight a bit over three hundred pounds, have a deep New York theater trained voice and look kinda like a Satanic biker. I have no doubt that the vast majority of those who have trolled and harassed me on-line would not say fucking 'boo' to me IRL.
In fact, because I can be a very charming fellow who can bullshit and gladhand with the best of them, I also suspect many of them might actually think I'm a swell chap. That aspect is reenforced by the sub-textual sense of relief that I'm 'much nicer than I appear'.
Those are the essential elements of what I call Primate Politics that are missing from the non-physical nature of da intratubes, all the core non-verbal information that we as a species have evolved.
