The Premier League have said that modern stadia have improved the match day experience for the majority of fans and I reckon they have that right. The demographic profile of fans has changed a fair bit over the years and consists largely of families and middle class supporters who have been, in part, attracted by 'modern football'. Perhaps those described by some, wrongly in my view as no type of football fan should really be considered as more legitimate than another, as real fans are now in the minority? It is this group of fans who seem more passionately in favour of a return to standing, partly due to nostalgia and partly because they've seen it work elsewhere.
I'd describe myself as one of the middle class section these days. I like to sit to watch football and I don't like to sing. I want to watch the football and go home. I'm not interested in the 'fan culture' aspect of it all. But I do think, provided it can be made safe as it would seem it can, people should be given the option to support their club in a different way to that which suits me. If it comes in and improves atmosphere then that's great. Even if it doesn't improve the atmosphere the worst case is that people have more choice as to how they show their support. I don't see a downside.
