Probably already been said but I think football hooligan behaviour in general is down to men being conditioned to suppress emotions so they don't know how to behave in a non-disruptive and non-violent manner when extremely emotionally involved in a situation. And this is why they shame women who say they enjoy football because we're able to feel passionate about it without kicking and screaming and swearing (most of the time
) and it makes them think we're just not arsed about it or are only casual watchers of the game.
