People were celebrating the courage and commitment of nurses and other front line workers - not lockdown.
If you would stop spending 25 hours a day in swivel-eyed, far right, conspiracy YouTube cess pits and come up for air in the real world, you would know that!
Just a suggestion.
PS - I watched Threads again last year and was impressed all over again by how good it was, and remembering how it tied in with the back end of the cold war, CND marches, and the 'Protect And Survive' booklets. The Sheffield setting was a factor too. Back in the 70s/80s it was government ministers and Town Hall executives who were going to be hiding in the bunkers. Nowadays it is the anti state redneck loons who watch the same YouTube channels as you!
