The Wednesday night "footbal club"
I had a very informative experience of the type of people that do this kind of mindless vandalism. My local pub had an upstairs room, that could be hired for functions. There was a "football club" meeting every Wednesday. Some of the supporters would turn up a bit early for a pint. I am not kidding, but the pudding head next to me could not even order a pint of lager.
"Pint of lager... Please"
"Would that be Foster's, or Carlsberg, Sir?"
A bloke in a suit with a briefcase came later, and everybody went upstairs. The landlord had his suspicions, and called the police. It turns out that the "football club" was known to the police. Nasty neo-fascists of some kind. The police prevailed upon the landlord to let them meet at his pub, because that way, they knew where they were. The locals all had a good laugh when the loonies weren't there.
The point here is that there are people whose stupidity is beyond imagination. No amount of scientific argument will dissuade from their views. They just like an excuse for a bit of mayhem, hur hur.
