I have a wee bit of a problem with the conspiracy theory:

Creationism is a faith-based religious belief. So long as the belief is honestly held by true believers, there should be no question of dishonesty…stubborness or stupidity perhaps, but not dishonesty per se.

AGW denial, on the other hand, could be several things:
1. A dishonest denial of proven facts of which the denier is well aware;
2. An honest denial of facts of which the denier is ignorant; or,
3. A denial of facts which the denier honestly believes to be false.

Is it really fair to tar the honest Creationist believer with the same brush as the dishonest AGW denier, or even worse, with the honest AGW denier?
In the absence of extremely strong evidence of malicious dishonesty, such a conspiracy should be advanced with extreme caution.
