The fact that so many people are saying drums should be banned (rather than us just making more noise than the drum) epitomises just how football fans have changed.
'I don't want loud sounds ruining my expensive match viewing experience, I want to turn up late, miss either side of half time at the bar, sit here in relative silence, and then leave 10 minutes early, because that's my right as a fan, it's my money and I'll do as I please'
OK that's a purposely extreme example made to make my point. However the fact is, whilst we may not need ultras with drums and flares, we do need better support in many home games. The Copenhagen game was a disgrace of a performance from city fans, all the home fans could have left early (and huge swathes did) and the atmosphere would have been no different.
Everyone will have their opinion on the subject, from "it is what it is" to "I can do what I want" to "people who complain about it are pricks" to "I'm not part of the problem".
The facts are though that players consistently say that great atmospheres help the team play better, we want our team to play even better and win everything (and complain when they dont), we can help them play better by creating a better atmosphere.
Surely, all excuses aside it's a no brainer.
