i agree, which is why i dumped all my gary glitter posters...yes, i am kidding.
it is a shame to realize what sort of jerks these folks end up being. i would point out though, that he's only living up to his name.
I can appreciate a poster... but meeting someone whose music you respect and then finding out they are a total asshole tends to taint everything associated with them...
There are bands I know that I liked that I can no longer listen for this reason... bad vibes!
