But that's kind of the point, regardless of what you think about global warming you should be wary of "you're either with us or against us" type arguments.

And for the record I don't know much about global warming, it seems at least plausible, and I certainly don't reject it. I'm just wary of the kind of argument from urgency that's become so popular lately in American politics (and I'm sure it's been an effective political tool since the beginning of time).
