I just chalk this up to a liberal musician. Not aiming at any musician here. But other than Alice Cooper...how many are there?
I have a very big music collection that I paid lots of money for over the years...and love music so I can't toss it. I had to quit going to concerts because these idjmoes can't help but interject their unimportant opinions in my listening pleasure...that I paid BIG bucks to hear. I notice it has really hurt their income since I went going. 
There was one of the Ramones. And, Ringo. But, I get your point.
And, anyone who listens to Mick doing anything but singing deserves the stupid drivel that they get.
