Kick It Out haven't said anything about Newcastle fans having racist tendancies or wearing tea towels is done for that reason. Taken from Metro: But Kick It Out – English football’s equality and inclusion organisation – are already said to be making plans to offer education workshops in Newcastle to supporters to explain how impersonating Arabs with their dress could be considered racist, offensive, or culturally insensitive.
I know nothing more than that. I have no idea whether Arabs find people wearing a token gesture of their traditional wear offensive or not. Kick It Out are suggesting that. I would happily acknowledge that Kick It Out know far more about things like this than I do.
