the thing is people don't realize what the group of people jones was playing to in the 90s was like. it was a militia movement. it was a group of people literally waiting to overthrow the government and put in a small-government, pro-gun, libertarian state. this is what alex jones was about originally. this is what his roots are.
these people were literally like a gang and were very weary of outsiders
bill hicks was an anti-gun comedian. big time. he NEVER would have been accepted, at that time, by right-wingers or people in the 90s militia movement (who at the time were spurred on by incidents like ruby ridge and waco).
shortly before his death, bill hicks got very interested in WACO and was working with kevin booth on the subject.

and later, in his stand up act

now it is possible that he wanted to change gears and become a part of this movement. it's possible he got really genuinely swept up in it, but knew he would never be accepted or be able to be any sort of figurehead of the movement with a history of saying the things he had said about rednecks, guns and drugs and all of the other stuff he talked about.
it's possible that he decided to take on a new persona in order to infiltrate this group of people, either with genuine intentions or nefarious ones.
it's possible that he was contacted by CIA (which is i think what a lot of people think)
it's possible it's a crusade he decided he deeply believed in
it's possible that he just wanted to make fun and poke fun at those people, but then eventually decided he believed in all of that stuff.
the only thing i don't count as a real possibility is that "alex jones" (a name that, BTW, is suspiciously common and "american") is really who he says he is.
sorry. it's the age thing in the end. that guy is not the age he says he is (42, if i remember right)
