My partner grew up in a Soviet Republic. One of the things she remembers from her childhood, was the willingness of some villagers to go running to the local Commisar over any divergence of the rules. They took pride in it. There was no grey area, no common sense, the rules were there to "benefit" everyone and to be followed exactly to the letter.
Recently I've come to realise that alot of Mumsnet would have thrived under a Soviet regime.
Some will argue, "but the rules we are being placed under are in place save lives!". Absolutely, but people back then would have been told the same thing.
As for the virtue signalling, the majority of people always seem to need validation of some kind. It happens continuously, so it's hardly surprising that it's going into overdrive now. You're not obligated to give it to them, but if others choose to then so be it.
This thread, whilst anonymous, was basically intended to be a circle jerk for people who are "above all that nonsense", so how is it really any different? Person A gets to feel good because they baked some bread for the neighbours and got some internet plaudits for it. Person X gets to feel good because they sneered at Person A and got some internet plaudits for it. Awesome, everybody can be happy.
