Maybe they just enjoy the show generally,not bitching about Jons voice and Phil X so call not fit in with playing. As long as they atract girls and women to the shows and men too,why not,minority but they are there too,shows will get good reviews.That doesnt mean that women are stupid and tasteless about music.
You are here like music critics when some album come up,you are not even there and you are the onea to call show good or bad. People who are actually there and listen the whole show and they good with it,they are happy but for you here they are probably deaf,blind and stupid.Let the people to enjoy what they want,not everyone is demanding like couple of you here.
