howwudufeel You seem to think that 'people carrying on as normal' means 'everything was normal'.
No it wasn't.
It was people trying to find some grounding in a frightening, unpredictable world. It was people trying to ensure their owns, at worst, survival (given that many didn't); at best, some sort of future for them and their loved ones.
Many took full advantage of weaker people; graft and corruption was rife. Fear, power games, and corruption - lurked the lanes.
'Blitz Spirit' was coined by the Dominic Cummings of the day.
My parents were primary schoolers during WW2. The shadow of it loomed over their lives, thus afflicted mine. However, they, like you, would probably have Brexited, because ' We won over the Hun', as their Telegraph would have reminded them on a daily basis. As they, and the pitiful Mail do, today. But remind them of the privations, the shortages, the impoverishment of their young lives, the lack of hope for a better future... (my parents went to east Africa in 1957...), suddenly would they start singing 'White Cliffs of Dover'...?
I think you'd be hard pressed to have raised any 'Blitz Spirit' in them.
I see 'Blitz Spirit' in Brexiteer slogans, like ' it will all be rather same, nothing will change' (er, so why Brexit? Separate issue) and so forth.
But 36% of the electorate brought this upon everyone. We aren't 'pulling together' against a common enemy, we're hating you for bringing this on us all; for your ignorance.
I can't see myself lobbing bricks through your windows, but don't you dare suggest I need some faux, manufactured 'Blitz Spirit' in order for me to forgive you, nay, Celebrate for what you mindlessly visited upon me. And mine.
