This protester protested effectively. Morrissey proved himself to be the intolerant bully we have sadly come to know. This was not a riot or the beginnings of a riot. I guess the dramatists in here need to feel that Morrissey was in peril from 2 placards!? How fragile he must be? Are Morrissey fans now silenced when they disagree with him? Yes, they are! This is another mis-step for Morrissey. It wasn't funny and it wasn't kind. He holds and promotes his political views to his fans. Fans, if they disagree, can and may voice their disapproval of those views - just as many UK fans have done by boycotting UK shows.
A man who would attempt to turn his fans on someone he is pissed off with - dangerous, but unfortunately, not unexpected. Agrression is not a good look for anyone.
