My brother-in-law is a republican. He's been his whole life, even before Trump. He lived in Salt Lake City and now, Mesquite, NV. He loves skiing, hiking, taking his boat out on the water, etc. etc. He thinks we should not fuck up the environment. But he also thinks that's secondary to corporations making profit, and that infringing on an individual's liberties (in this case, the liberties of a CEO to steer his company) is the same as losing one's freedom. In his mind, not a conflict at all.
I do think he's become increasingly skeptical of facts and science that he thinks come from "the left". He sees it as manipulation by one side to infringe on those rights. To be expected due to his media consumption for sure.
But I also think the easier answer is: the people they hate thinks saving the climate is good, so they think it's bad.
Why is the environment a ‘left’ issue? Why would someone with ‘conservative values’ believe that environmental issues should dismissed and all science and common sense should be wholesale ignored? Is that a ‘conservative’ response? Is that a ‘moral’ act?
