> I wonder, if they managed to alienate people without a car and very low CO2 footprint, what demographic is actually left to cater to?
With climate deniers and conspiracists I always suppose they hide their real stance and it is revealed through small hints they let out. I strongly believe these small hints are baits to see if the other party has the same beliefs. They will be lying until they think there are in like-minded company (or are too drunk and let it out).
Yeah, I have been burned hard before by climate and covid deniers who lied right out to my face. They are dishonest and advance in disguise (with loaded questions and fake scepticism and the whole arsenal of arguments coming from fabricated doubt factories).
