I'm not against environmentalism, I think its political advantages are already enough for it to be worth pursuing. If we could have enough alternative energy to stop dealing with Arabs and Russians, and potentially avoid a resource war with China in 20 years, that's great. If it cleans up the world a bit aswell that's great too, no one likes smog in their cities. I'm even willing to believe that most scientists think global warning is real and harmful, but the taxes and shifts in industry are about power and the actors behind enviromentalism will only use it when there is something to gain, I don't see them meaningfully attacking fats. I think that's what I mean with half-hoax, both potentially true and dishonest at the same time.
