I can give you another good example related to different language and culture which can in some circumstances raise the same issue ; we all have the so called "First Name" "Last Name".
In UK we have David Beckham, Ryan Giggs, Raheem Sterling, Paul Scholes etc.
In Romania we have 4th ref Sebastian Coltescu, Ovidiu Hategan and so on.
Beckham, Giggs, Sterling, Scholes, Coltescu, Hategan .. All second names if I am not wrong.
Would you be surprised to know that in Romania we have second names like : Negru, Negrea, Negrescu, Negroiu, Negras,Negrasi, and so on and so forth? None of them would be other than eastern europeans, none of them black people. None of them obvisously would be upset if you call them Negru (meaning black) ; they do not have that sensitive fact or perception related to the term. So it would be very easy to be unconcious of some remote topic which is problematic for other people.
If one of the refs would have as a second name Negru - so many potential problems that could arise , if you call him by that second name, right? Anyone in western Europe could feel bad about it ?
