Everyone just needs to stand back and get some perspective. But that seems impossible in the modern age of microaggressions and critical race theory.
I'm convinced I've seen a joke on Family Guy/American Dad about this exact thing, but I can't find the clip.
Anyway, seems to me the fourth official has went for what was, to him, the most obvious identifier.
It could be racist, but then if there was one white guy and a group of black guys then he could easily have said "the white guy" in the same scenario. Who knows.
On balance, I think it's subconscious racism. An overreaction too possibly but it's the times we live in, and unfortunately the word in Romanian sounds like another word in many other languages.
