Oh God, another internet petition. Because these have proved so successful in the past, haven't they?
If you were in that area of the ground and found his celebration offensive, you should report it to the police (and then slap yourself around the face for being such a soft arse).

An online petition will achieve the square route of fuck all. Of that I can assure you.
