I don't think we had a minutes silence for Remembrance Sunday until the 2000s or, to be more precise, until the the British death toll in Iraq and Afghanistan started mounting up. For what it's worth I fully support the poppy appeal and know people who served in those conflicts but fundamentally I don't think we should do more than carry a poppy on our shirts. Playing the last post and having people marching about laying wreaths is a sort of performative fetishization of the armed forces that we've imported directly from America.
The whole concept of a minute's silence has lost it's value now. They exist simply so that global brands, which is what Premier League clubs and the league itself are, don't get criticised for failing to suitably acknowledge some death or catastrophe somewhere in the world. It's defensive PR and has nothing to do with remembrance.
Added to the general sentimentality / emotional incontinence of British society in general we find ourselves forever clapping and remembering when, imho, most people just want to watch a game of football as a distraction from all the ills of the world.
