I've puzzled over agonized progressives who proclaim their need to re-understand the world they live in. It seems sincere, despite the fact that all that happened was they lost a close election between two unpopular candidates.
But their belief that they are on the side of history did take a hit. The mystical embrace of the forward march of history is a common progressive belief. It's why they call themselves progressives - because they have allied with the winning side which is the inevitable future. All this goes back at least to Marx.
