I watched the you tube video of AC Milan walking off the pitch due to racial chanting, but some idiot in the comments writes this:

If they pay good money to see Italian football, they have the right to see Italians on the pitch. I don’t see any reason to give support to blacks, Arabs or Eastern Europeans when you don’t feel any connection with them or even can’t pronounce their names. I don’t watch football at all for that reason. It became too expensive too see some foreign mercenaries play while your own countrymen play in lower divisions because it’s much cheaper too kick five blacks out of a tree somewhere in Ghana
