@HistoPol @adriandaub @davetroy And Heinlein's DD Harriman. They, I think, lack even the limited (necessarily for fictional characters) empathy shown by those characters.
I suspect Jubal Henshaw and Lazarus Long play into their self images as well. All in all, my gut feeling is that Heinlein may be the strongest driver of their self-mythologizing, but they still seem to miss out on his empathy and anti-authoritarianism..
