I'm lean moderately libertarian, but understand what a natural monopoly is. It's not libbys per se, more a Tea Party thing.
Some people are so seduced by the simplicity, the elegance, of an ideology, that they never pause to consider whether it is actually *correct*. They don't want to let annoying things like facts mar the beauty of their True Beliefs.
Having tried to teach them a few things, I have learned the hard way that they are paranoid, ignorant, and completely reject any information that doesn't conform to their beliefs.
"97% of scientists believe man-made global warming is right."
"See, it's not unanimous!!!!"
"If 97% of doctors told you the mole on your cheek was malignant, wouldn't you get it removed?"
"You're a liberal elitist."
They can't be bargained with. They can't be reasoned with. They doesn't feel pity, or remorse, or fear. As far as I can tell, they are mentally-challenged Terminators.
