Conspiracy theories, the past when everything made sense, nationalism without socialism to reach the goals socialism couldn't deliver on, etc.

Though of course, the seeds of future political itineraries were already present and not fought against when they were leftists. Those who became libs having a strong stance on freedom and democracy and how socialism could expand it, the future fash being content with having a strong and Well-functioning state, etc. Genuine proletarian desire to overthrow capital is not the first priority of at least a large minority of the left.
