Woah, there.
You can have one section/stand for ultras (some of whom might occassionally don a mask or balaclava) who chant intimidatingingly (but also with humour and positivity) and have a pyro display or two, while at the same time have the rest of the ground available to kids, families, old folks and everyone else. You don’t think the game is open to kids and women in Scotland, Germany, Scandinavia, Belgium, Holland and so on? Do you really think ultras culture causes nazi salutes and stabbings? I mean, come on.
