Agree, thats why I say that for them "white" means basically protestant germanic.They don't really consider Russia white, though, as can be seen in the many examples of nazi-speech of how the Russians are actually closer to "asiatic hordes" than to "white civilized western men".
Neither orthodox slavs neither catholic mediterraneans are consider white by the US/UK. The slavs are seeing as asiatic and the spanish portuguese as half africans.
Only thing is that mediterranean state are totally dominated and they dont care any more about hating them. So they keep their hate for the only ones remaining independent in Europe that is Russia and in a lesser way Serbia
