I don't even think in England you would get in trouble just for swearing. It seems like it's headed more towards American sports level of censorship, which is even worse (just last week I got chastised by a steward at a hockey game for chanting "LA sucks").
This really upsets me that we might be nearing the end of the atmosphere in Italian football as we know it. In with the new era of club-sponsored tifo displays (La Liga) and sitting down & being quiet (PL).
