Yeah, I agree with that and no doubt the thread will eventually just end up going round in circles again. Then the arguments will kick off, and the thread will be pulled. Repeat ad nauseum!
There are undoubtedly a fair few journalists who will be relishing the opportunity to stick the knife in, and it will probably get an undue amount of publicity as a result, which is why I find it frustrating that Guardiola/the club have imo given them a bit more ammunition rather than drawing a line under it. I don't agree though that it's only become a story because it involves a City player. It would be in the media if any profile player had done it.
Don't forget Sterling called the media out on their racism so as much as they all applauded that and made the right noises, you can bet deep down they would have been fuming and waiting for any opportunity to strike back.
