2. Denial is far easier than acceptance for simple minds
Denial is little more than saying "La-la-la, I am not listening to you."
Acceptance means have to react to and adapt. Accepting that one's lifestyle is going to be seriously impacted for years to come--probably all of them--is depressing if one is tightly connected to the material things.
Climate Change - "Al Gore isn't lying, and he's just as fucked as the rest of us?"
Evolution - "You mean all that fucking money I gave the Church is for shit?"
Math - "You mean Nate Silver was right because he went to school?"
