You're a naughty troll these days, Diez.
It's like those who do their private Nazi dress up parties. People then get really bothered because someone is doing that in private. Who cares about the offensive theme if it's not in public? Is it different to having a Harry Potter party? Swinging? I don't know which is worse, it's not like they are glorifying it, just something consenting adults do.
It's only when it's a politician or someone in the public eye that people find out about it. They should use a bit more common sense. I just think Smalling's costume is hilariously dumb from him, but then he is a footballer.
