I don't really understand what some people want/expect.
People talk about the atmospheres at games abroad, despite knowing that English football culture is not like that found in other countries. Any attempts to replicate European fan culture, such as the Fanatics at Palace or Union FS at Leicester, are often met with derision and accusations of being 'plastic'. God forbid anyone bring a drum to a game, despite it being commonplace at many grounds on the continent.
So what we want is people singing for 90 minutes regardless of the quality of football on display or weird kick off times, and it has to be completely organic because we don't do any of that plastic organised shite. Sound realistic to you?
Then of course you have people moaning about the atmosphere who will be sitting on the Family Stand or the BLUT. Basically sat looking over at the punters on the Kop and judging them for not being as loud as they'd like them to be. Naturally such people are doing fuck all to contribute to the atmosphere themselves.
This topic rears its head every few months or so. If you don't like it, maybe try to do something about it?
