Bill Hicks became far more fearless. Alex Jones still holds onto a lot of fear which is why he rages so much. Not saying that it's good or bad, it just is. I think Alex expressing his anger on air helps a lot of people realize their own fear in regards to the destruction of this world. You cannot conquer fear until you face it.
Bill Hicks and Kevin Booth's production company produces Alex Jones' movies. Therefore it seems likely that Kevin Booth supports RP, and thus using guilt by association it would seem likely that Bill Hicks might also support RP.
