...And yet there's a correlation between what a liberal believes is right, and what conservatives believe is right 50 years later. You'll be hard-pressed to find a conservative who believes we should re-instate slavery. And yet when the Founding Fathers proposed to make a black person count as a fraction of a vote, it was seen as radical liberalism. Seems to suggest liberals are the force of developing morality.
Conservatives serve an important function. That function, I believe, is to pace the speed of progression in such a way as to not jolt society too hard. But ultimately, they almost always lose. And the conservatives of the next generation believe what the liberals of the former generation did.
It is understandable older people are more likely to be conservative, as the plasticity of the brain reduces. What kept them alive for 40+ years must be working, right? But if it were left at that, it would be the death of our species on an evolutionary level. Our brains are our only claim to fame. Our moral development is the only thing special about us. And it is essentially the difference between the developed world and the developing world.
Appeal to authority is a classic sign of the conservative mentality.
