I think this subthread is a good summary of why we should just leave politics out of LW, and why trying to summarize a single dimension of difference is hopeless.

So I'll continue :) Here goes the anti-turing definition (each side will agree it applies to the other, but not to themselves):

Progressives/leftists believe it's OK to define rights over things that don't exist yet (say, food that isn't yet planted or care from a future doctor who might prefer to golf that day instead of exposing himself to your disease). The conservatives/rightists think it's OK to define rights that make it easy to ignore others' suffering.
