So tell me what the FA can charge Fernandinho with?
I don't know, i'm not the FA. But they found a way to ban Cavani for saying a word that was not even English but translated as 'racist' in England. So if they want, they could charge Fernandinho for tweeting an offensive comment. A big
if they want but since it only offended a few United fans, probably they won't.
Which only shows just how ridiculous the Cavani ban was. The FA made a mistake (granted it involved a very sensitive subject to the general public) and because of that, of course people will draw a line and make a connection to that case when something similar happens. I don't know why you find it funny or silly, as i said they're the same thing and both are offensive but this time it's a different kind of offensive as it didn't involve race, that's the only difference.
