Would also say that if there was anyway of it being brought into football it shouldn't just be the FA it should be at least FIFA bringing it in and just imposing the ban on fans to chant anything derogitory against them or it would result in Bans from stadiums, Club Fines, etc exactly like the racism rule then maybe it wouldn't cause as much of a problem (obviously there still would be a bit from fans and time to get used to it)
Thing is FIFA have done the fines before, and the amounts were absolutely pathetic. But the bans, or playing behind closed doors policy should be more firmly introduced. Think it's one of those things that's going to be really hard to prevent. But to stand even a chance of preventing it, maybe the punishments have to be more severe.
