I am trying my best to word this the correct way but will probably fail as I have never been good at expressing this.
AIBU in thinking the UK's "obsession"? with deferring to "wartime spirit" is somewhat odd considering the majority of the country most likely have never experienced it? People who were born the year WW2 ended, for example, will be 75 this year. Many of us don't even have parents who experienced wartime or this "wartime spirit" that we are all supposed to be falling in to as a nation.
I am NOT suggesting that we shouldn't honour the people involved in these wars, nor am I suggesting that the wartime spirit at the time wasn't amazing......just that its a rather strange point of reference for a population who may have never experienced it.
