Agree with the overall tone of the OP and some of the points. I think the thing that you are talking specifically about are extreme opinions that aren't considered, which I also dislike heavily.
Anyway, do you know why we will never have an Aris like stadium? It is down to one reason only - the mentality of the fans.
In these types of clubs, people buy their ticket to be part of a group. They understand that the fans have a job to do just as important as the players, and they purchase tickets to say that they helped their club.
In England, fans buy tickets to watch the match and moreso, be entertained. We don't think about how our singular actions can affect the club as a whole, or the team on the day. Due to this, we sing because WE want to enjoy it, not because the we think it is us being part of our club.
At Aris, there is an attitude that the guy who buys a ticket in back of the Colin Bell Level 3 is just as important as the guy who saves a penalty.
In Aris, they are part of their club's product. At City, we are consumers of the club's product.
Basically, our fan mentality is completely wrong or more accurately it is incompatible with a good atmosphere. This is also why any sort of Ultras was never a possibility, we don't see the connection between us in the stands and them on the pitch.
Dave is going to think I'm picking on him or something again, but he made an interesting point somewhere. He mentioned that this game is heavily based on player motivation (something which I disagreed with, but I do think it plays a part). I have never seen him at a game, but I'm 100% sure that every game he goes, he'll be amongst the loudest there because he seems to understand the symbiotic relationship between fan noise and player motivation. He's as far away as you can get on this forum from constantly positive, but that doesn't mean that this happens at the match.
There is very little connection between the opinions expressed on a forum and at a match. There is, however, a connection between events or groupthinking that starts on a forum and spills into the matchday.
Those who need to be reminded about how powerful a forum can be to the matchday atmosphere need to look at the Neil Young tributes, or the Poznan or (what I imagine the next craze will be) the Mario Hats.
However, if we want a better atmosphere, we need the club to meet us halfway. The away fans do NOT generate atmosphere, this seems to be a myth that others trot out. The guys who naturally gravitate to sitting where the away fans are are the guys who generate the atmosphere.
If Liverpool can have waving flags, if we can have occasional ticker tape or streamers, why can't we have them every game? The singing is our job, and we have a horrific sense of self entitlement that needs to be removed recently, but there's no reason why we cannot get a pressure cooker atmosphere. Hide the away fans in the rafters or something like the Geordies do, and stick all of the singing fans together. Give us back a Kippax, so we actually have an identity in what is generally a bland and very corporate stadium.
We can build an atmosphere if we try, and it can change our mentality as fans, but only we can do it. There are plenty of posts on here proposing that we should do this and not enough who say "ok, I'll bring the tickertape for section XXX" or whatever. It doesn't magically appear, either we make it happen or nobody does.
