If you have paid for and chosen to sit in the Family Stand then it is perfectly reasonable to expect others around you to tone down their language HOWEVER around the rest of the ground it is foolish to expect everyone to behave similarly. For many of us going to the football is a place to let off steam and behave without having to watch yourself as you might during the week at work, or around the mother in law at home.
There are always going to be people who take it too far and make themselves look like morons but you just have to accept that it's part of the game, you can't go forbidding them from expressing themselves. There has been enough fun taken out of being in the crowd as it is what with there being no roof, not being allowed a beer, being forbidden to stand up etc.
If you don't like it, sit somewhere else, don't play the concerned citizen and spoil someone else's enjoyment of the game.
Apart from anything else a bit of creative swearing can often be very funny and a rallying cry for a quiet crowd
I expect to hear swearing at a football ground but to keep calling the ref and linesman c--ts constantly and at the top of your voice is not on.
If you did it out on the street you could be arrested.
