What do you rely on when you don't have "empirical evidence"? Faith in political agendas.
Indeed.......the Rolling Thunder guy would gleefully buy a big old bag of dog poop for $1,000.00 a pop if it was packaged just right!! These people grow up in thatched cottages and fall for every single PC bullshit thing hook, line and stinker.
I bet you could find a NOAA graph during the 70's that predicted an ice age. The left has a graph prepared for every political event. That''s how they they are compensated with taxpayer funding.
