It's more than the doomsaying too.

Here's a personal example: Washington State had a ballot initiative to add a carbon/gas tax. The initiative included a reduction in the rates of several other taxes, so as to get anti-tax people on board. I didn't vote for it in part because I know that the tax reductions are just temporary and that adding a carbon tax would just make the taxes in the state higher long term.

It is in part because of this that I am more open to the idea that scientists are getting things wrong on AGW. A world in which we all believe AGW is an important issue we need to tackle is a world in which liberties will be markedly reduced. I, and many like me, do not want that kind of a world, so it opens us up to any possible counter to it.

If, instead, the ballot initiative that would add a carbon tax did something like eliminate a different tax altogether, the issue might not be so big since it would signal that the path those who want to tackle AGW is taking does not involve marching more quickly towards totalitarianism.
