thanks for linking that. yes indeed Liberalism (capital L) is the best technology yet invented for preventing civil war, which is otherwise the more-or-less inevitable outcome of tribal politics.

the most important methodology of Liberalism is the cultural norm and moral importance of unfettered freedom of speech, expression, and association. The moral and normative importance of free speech cannot be understated. Losing this as a norm has eviscerated the left leaving them as noxious authoritarians sliding down the slope to Mao-ism.
