Very, very strange how fans observe other fans behaviour these days (even fans supporting the same team). Any little thing is pulled up on.
I don't understand the dick waving arms race thats developing.
It seems the media have successfully infiltrated the ego's of football fan 'ultras', who are now only content with a fan version of North Korea being put in place. Fan shaming - now there's a weird development.
When fans leave, how they react to the game, how they react to players, how they understand tactics, etc, really isn't up for discussion. They pay their money and they make their choice.
Football is, ultimately, an entertainment industry, and fans add to the entertainment.
