Writing last month on a completely unrelated topic, I recalled an incident from back in the day:
This reminds me [I wrote] of a meeting I attended some time in the 1970s, at which leading figures in the far-left organization to which I then belonged were trying to win over members to vote for the 'political tendency' for which they were speaking. Vexed by something said to him from the floor, one speaker denounced the partisans of the main opposing tendency as being 'a petty-bourgeois rabble'. He failed to win anyone with this observation.
I now feel I ought to insist that it was a memory and not a prediction.
