Know exactly what you mean about one of the non bigoted clubs being the ones that will be punished. My point is that we all know who the main culprits are, and it isn't as if the evidence isn't stacking up against them week after week.
Powers that be need to grow a set and set a precedent by punishing the clubs where it hurts. If the lesson isn't learnt, then punish them again and again until the penny finally drops that religiously bigoted songs about events from centuries ago have no place in the 21st century.
