No musician deserves to not be able too play music on stage. If you do not like a musician/band don't give a shit about them. No one is forcing anyone to do or take interest in anything. And if someone has such a problem with a musician get a guitar and do it. It could be a motivational tool if anything if you think some musician is a piece of shit and sucks or whatever, just like some shit job,people,circumstance, or situation.
