I can’t help being part of the zeitgeist
But (maybe on a tangent here), it is a bug bear of mine that, whenever there’s stuff like: Steel Walls, shutting Bramall Lane, change of kick off times etc etc the first thing is to blame SY Police, SAG, whoever and it seems like the reason for these measures; the nobheads get off Scot free in the blame stakes every time.
As for how you stop it, we’ll, it’s a huge question but I think very much an element of self-policing. Let nobheads know it’s not acceptable how they act; make them social pariahs at games.
Its also come from learned behaviour from the older generation; how many times are there nostalgic posts on here about the 70/80’s etc. All well and good but the aftermath of that behaviour is the infringements on our civil liberties we get from SYPD and other forces today. Some acknowledgement of that from the older generation rather than constantly blaming the police from trying to stop innocent people getting their heads kicked in might be nice.
All pie in the sky I know
