What was he like as a person? (I don't know about now, so I will go with what he WAS like, and proceed from there.)
He wasn't terribly imposing physically. However, it was not beneath him to consider violence as an option-nor threats, either. He was hardly alone in this. I once had a run-in with the late T0m M, years before he committed suicide because he couldn't stop lcm from nailing Mrs T0m M. He was a larger dude, and wanted me to stop an uncomfortable line of discussion (this was at ROA '89, when 1/5 of the previous year's attendees showed, and most of them left twi shortly after that event.) He tried intimidating me physically, and when that failed, he tried to get a rise out of me by threatening physical violence. I bugged him more by simply getting calmer and calmer the more he tried. His final attempt was to try to claim I was unemotional because I wasn't reacting. (No, just smarter and with better mental discipline. Plus, he grew up in the suburbs, I grew up in the 'hood.) Cgeer had no problem similarly trying intimidation OR threats, but was not a physically imposing man nor a trained fighter. So, he didn't default to it all the time, and he needed to use things to accomplish it.
Cgeer and lcm (craig) were both the 2 biggest vpw-worshippers in twi. That's why vpw- who loved how they smooched his metaphorical tushie- made them twi elites. lcm was made his successor, and cg went from vpw's bodyguard to in charge of a twi property in a different continent than lcm. (When lcm and the others pushed the retired vpw to the side, vpw ran to cg to cry on his shoulder about how he was being neglected, and how this would destroy twi because they were forsaking Gawd Almighty by ignoring him they way he ignored others who had retired.) cgeer was used to taking care of vpw's dogs (vpw never took care of them), and walking around armed with vpw at public appearances. cg claimed-and I believe he was not lying- that he had been prepared, if necessary, to act as a human shield to take any bullets fired at vpw if something happened.
So, how did cg intimidate people? His primary methods were threefold: 1) brandish a firearm, which is a crime in the US 2) use the dogs and menace them (menacing is also a crime in the US) 3) send someone else to intimidate them
Others in twi were more fond of the "send others" than cg, but he seemed to like the feeling of power he got when he instilled fear in people by threatening them with a gun or big dog.
Mind you, that was 30 years ago, literally. He's 30 years older, and doesn't have the physical power he DID have, such as he had. For someone who only feels secure wielding the power, to live without it is to live in fear. So, he naturally would go into hiding, and lay low or surround himself with security. For someone who is aware of how many lives he hurt, both in acting as a de facto procurer for vpw and in his own capacity to misuse power, he knows there's people who might harm him if they had the change to settle a score, and he's not young. So, that alone would send him into hiding.
So, he goes into hiding, and cultivates a sense of mystique about him, making it look like the hiding is anything BUT the cowardice that it is.
Mind you, the fact that he was more than a little crazy- and thus unpredictable and lacking self-control- was another issue, and people could be scared he'd go off without warning...which he sometimes did in imitation of vpw.
All of that means he's not as scary as he was 30 years ago... and without a gun or a big dog to back him up, he wasn't really scary back then.
