I have lived with guys who did Deca, winny, etc. and he had more of an "agitated" look to him in addition to the anger. I would say there is more than juice involved. I don't know the man or anything about him other than his YouTube video's, though, so take this as an isolated observation.
I gotcha JWG! The sarcasm on my end is a bit tough to decipher on the net, he really seems passionate about this, just (IMHO) he expressed himself in a mode that a line doc as I am could relate to, and not take any offense to his crude and vulgar method of expressing his disappointment in our leadership, but the masses who aren't used to the "in your mother $&@/%# face show" starring James Yaeger are easily put off and steer clear of these A type personalities due to his aggressive and hard nosed charge.
