Please refrain from spreading nonsense you clearly know nothing about.
Nationalism isn't race. You are losing the debate changing goalposts doesn't work.
A Croat will never agree they are the same anything as a Serb.
Your limited understanding smushed millennia of history into the primitive categories your country developed in it's short existence. They have zero meaning here and your continued ignorance serves as example why it would be better for everyone if you stopped talking about things you know nothing about.

You lost the debate here. People classify themselves in a million ways. But we are talking race. Next you'll say there are no males or females just Croats or Serbs. No blonds or brown haired people just Serbs or Croats. Lol.
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.
