You just can’t get anywhere with this Alan.
My parents are elderly, 86 and 84 now, still attending but have been STH’ers since the move 20 odd years ago, They are from South Wales and Kilmarnock in Scotland, and relocated to that area and wanted to watch live football. Their closest professional team is Luton, but that is a shithole and quite frankly fairly intimidating for them. MK Dons provided an opportunity for a clean, shiny, modern, safe football experience for the likes of them and anyone else in that area that doesn’t have the same sense of intense loyalty and passion to the team you have for life or the associated morality that comes with that either.
Just to labour the point, that’s absolutely no defence of those choices and as said, there have been ferocious debates over the last 20 years or so, and whilst I don’t get it either I hope that makes some sort of sense of their distorted perspective.
