I had exposure to him one time, an all day clinic at UNM in Albuquerque, when I was living there. To say that Russell, on that day, was a quietly intense, perhaps obsessive, dude wound not be exaggeration. But there was never any doubt that he knew exactly what he was talking about, why he was talking about it, and that his logic was in perfect alignment with his premise.
Anybody who "makes fun" of the LCC does so at their own risk, imo.
