I didn't read the entire thread here, work has kept me away for the last couple of weeks, but I think I've seen this all before. Several times.
Mike Portnoy is the only "celebrity" I know of who is so emotionally fragile that an incident like the ADTOE shirt on someone at his signing event would knock him so far off the tracks.
I can only speak for myself as an addict/alcoholic, but Mike seems to display a very high degree of "Self-Centered Fear" where he seems to turn otherwise meaningless events and situations into some kind of attack on him
Self-Centered Fear is extremely common with us alcoholics. Everything is about me, me, me....poor me, poor me.....eventually, if he stays on this track poor me is going to become "pour me
another drink"
