Again, you don't understand. Race is absolutely meaningless here. It is a concept developed in the US a few hundred years ago to justify slavery.
You insist it maps to our continent, which has had identities develop long before we came to invade your part of the world.
It does not, no matter how much you insist. You told me it's what people would pick on forms. I showed you the form. It wasn't even an option.
There is no debate. It is just you trying to map your racial animus to a set of societies that based on your continued confusion are much too complex for you to understand and me trying to educate you.
Croats and Serbs are just the most obvious example. We can also play the same game with Poles and Russians or any number of ethnicities.
