This crap was well advanced in the '50's when I was in university. It has just gotten more and more pervasive, down to the primary and secondary schools too.
You’re absolutely right. My kid in high school recently had to do a presentation on what she thinks of global warming. She thinks it’s all a fraud and a hoax, but the teacher told her that she had to deliver the presentation from a pro-global warming perspective. She fought it, then delivered the speech, then told the kids in the class that that’s not what she really believes. A large number of the other kids were on her side. I don’t yet know what grade the teacher gave her.
