One aspect of this that the author doesn't touch on is the "Bush factor." I am absolutely convinced that Bush's skepticism about global warming is one of the factors that motivated global warming proponents to ratchet up the rhetoric and demonize anyone who expressed any reservations about the reality, causes, or effects of global warming.
I agree. If Bush is for it, then you have to be against it. There is never a middle ground where you can meet. You have to fully demonize Bush and everything he believes in, period.
