I won't speak for Boober69 but I can give you my response.
My answer is: No, I don't agree with his premise that the world is doomed.
I would also add an important reminder: TERB is a website for adults.
Every person who visits this site should be old enough to understand that saying Moore is right about the green energy scam (and he is) doesn't create an obligation to agree with everything he has ever said. Indeed, it doesn't create an obligation to agree with everything that is said in this one movie. Adults have no problem understanding that.
I'm sure some of the lefties who agree with things David Frum has written about Donald Trump don't necessarily agree with everything Mr. Frum has ever written.
