So what does your State do if a kid from a school district with crappy sports teams moves to a school district where colleges recruit heavily? Do they let him do it? Probably not. What's the difference? If I'm a soccer star who lives in a shit-hole country and I move to Bulgaria so that I can compete in international competition for the Bulgarians, why should Bulgaria allow that?
And why is this declared a "racist" remark? That is a moral conclusion that no journalist is qualified to assess. Bulgarian football is for Bulgarians. What is racist about that?
The same issue arises in the U.S., and I think it's bullshit. If an African American is on the team, fine he is American. But if some kid moves here from a foreign country because he knows that we suck at soccer and he can be a star? Bullshit. The team should be comprised of Americans. Nothing racist about it. It would apply to Germans, Brits, ...whatever.
