Well said @CoffeeWithCheese
For many of us the AD threads were a little bit of light in the darkness/madness.
I don't live in the UK and there were some very supportive threads about the pain and frustration of being forcibly prevented from seeing family in the UK.
The "dementors" loved a good "what's happening in other countries" thread.
I was told, in no uncertain terms, that I had no place having an opinion as I am not a UK taxpayer (WTF!? - yet another "imagined" rule).
It was comforting to see that there were still some sensible people in the world.
By OPs logic, I should be asking MN to delete all the "well you shouldn't have moved abroad in the first place, serves you right" posts as they were deeply upsetting, but being a grown-up I just hid the most bonkers of the threads.
All of the threads should be left as a record of one of the weirdest periods we have ever lived through (and I'm quite old now, so there's lots to choose from!).
