He was very much in the club. I've read about this from several researchers. You might be able to find some of the work exposing him on Jan Irvin's Logos Media website and on Logos Media archives on youtube and altcensored.com. Some of the richest deep context came from Irvin's many excellent presentations with Dr Hans Utter (on altcensored) but that's a lot of material to wade through. McKenna also made some bizarre statements like in the future there should be far fewer men allowed, i.e. the population of humans should be almost all women.
