You are right about the bias, of course, though I think there's a much stronger bias in favor of theories you've come up with yourself.

I think that in the context of climate science, if you make a statement that you disagree with "GW theory", you are making a statement that is very close to a blanket denial. Which specific facts of the theory do you disagree with, and what is your alternative? Are you disagreeing with the IPCC number for the climate sensitivity? Or are you disagreeing with the idea that anthropogenic global warming can be true? Those are very different, the first is well within the scientific mainstream, the second is not.
