Are the listeners angry because they are unhappy leftists? Leftists are always unhappy.
They clearly have bought into the claim that mankind is no good and the cause of climate change. Not true.
Maybe some of the listeners will come around to the conclusion that the world is in the grip of a climate cult. All they need is sound and objective science. Common sense will help.
Climate change is real. It is caused by the Sun.
The unhappy listeners are well-organized professional complainers. It doesnt take very many noisy people to make an outrage. Like a room full if kids, the screaming ones get all the attention. A couple of people can make themselves look like hundreds using modern technology.
“Global warming” and “climate change” give a lot of losers something to rally around, especially in post-Christian America; it is their religion, and they’ve found a purpose they’ve lacked since the Vietnam War ended and the whales were saved. Seriously.
