Yep. That's one of the big differentiators. Their views are not based on facts, they're based on dogma. "Global Warming" is an excellent example of this.
Conservatives have a few hang ups of their own. But, IMHO and in general, I think that conservatives are more fact-driven, and liberals are more emotion-driven.
And, I'd argue that's a good thing, until the balance between the two sides gets too far out of whack....which is where we are right now.
The so-called 'war on drugs' comes to mind. Conservatives normally make arguments based on facts, but the Drug Warrior crowd that self-identifies as 'conservative' always falls back on emotional arguments to justify tyrannical overreach in the name of the WOD (ie. 'if just one child can be saved' yadda yadda yadda).
This goes both ways, however. This issue has become so politicized, that the facts don't seem to matter to either side. Evolution, the same thing.. sigh...
