Paul McCartney is a jerk.

Paul McCartney is an immature, uncurious, and aggressive statist.  Yes, he was in the Beatles.  We all liked his music.   Does that mean that we should consider his uninformed opinion on the environment more than anyone else?  No.  What is his expertise on global warming/climate change?  Absolutely nothing.  However, what is quite clear is that he, like most statists, likes the idea of controlling the people.  Just as he was able to get girls to swoon to his music, he would like to get a continent to shrug as a result of his overbearing socialist policies.
