Ok, I can get sort of disagreeing the wildfires are from climate change - that’s a couple of logical steps you have to make. But “It’s not causing anyone to cough” is plainly ludicrous. It was making me cough when I went outside.
“It doesn’t smell bad”? Maybe they have COVID and lost their sense of smell altogether? It certainly smelled bad to me. And if you thought it smelled great - wow. I just don’t ever want to be around you if you like those sorts of smells. I can’t see it actually working with anyone who’s ever been in wildfire smoke before - like you don’t need science or education or anything to notice if it makes you cough, or tell something doesn’t smell great.
I think it is probably similar to people who proudly proclaim that they have always been bad at maths or that they know nothing about computers. It helps them fit in with their in-group.
