They're back. Rosell allowed them back again, however they're not the group they were a long time ago.
They were banned for a reason though. The Boixos Noix went through a major change in the 80s, 90s from an socialist-liberal ultras group to a fascist criminal organization vastly involved in the organized crime in Catalunya.
Only a portion of them were allowed back, and I still don't think they can display affiliation. So they're not really "back". I can't remember where I've mentioned this before, but my friend's dad was a member and he passed away recently still with a stadium ban.
Atmosphere is pretty bad compared to other big clubs though. Let's say ManU or any english team for that matter. That's certainly something Barcelona should try to improve, atmosphere.
A lot of English stadiums are ghost towns, to be honest. Part of the reason why I have explained below, but some are just dismal even with what they've got.
Anfield is really overrated IMO.
Anfield isn't overrated in the context of English stadiums. There are fan regulations in place, I think the Liverpool fans do a great job with what they are allowed to do. I was admittedly underwhelmed by the atmosphere when I went there (in this case, it sounds better on TV) but it's not just down to the fans not being passionate enough or anything like that. Barca also have a certain amount of restrictions, not allowing fans to create their own tifo displays is probably the biggest one, the mosaics are made by the club so there will always be a certain corporate feel to them I guess.
I am probably also spoiled after going to a Milan derby so stadium atmosphere almost anywhere else will pale in comparison.
It shows a fine degree of maturity on the part of the Camp Nou crowd.. Its great that families can come in and make it a real festive atmosphere. No rowdiness for me.
You can have both, some clubs have family sections that are on opposite sides of the stadium to where the ultras would normally sit, for example. And I don't think he's talking about allowing violence or anything like that, a group of fans can be intimidating and strike fear just by being loud, chanting, bringing in banners, etc.
