From Dumb Jon in the comments here :
Liberal world view is based upon the idea that we are at a unique moment in human history when now, for the first time ever, a civilisation can get by without the family, a shared narrative, a code of honour, objective truth, a sense of consequences or, well, any of the other 871 things the Left sneers at whenever traditional values are mentioned. Apparently, every civilisation that has existed in the past 5000 years has been a ghastly mistake.
Well, now we've got a chance to test that hypothesis.
