Dont tell me that this is important. Maybe you want to call them Yugoslavs?? You must be a true communist if so.
But let me guess you dont want to call Serbian people the Serbs because you are afraid to not offend Muslims???
No I want to qualify whether they are ETHNIC-Serbs or simply people born IN SERBIA.
One could be BORN in Serbia and be an Ethnic-Bosnian or Ethnic-Albanian, and yes the former name for the territory could impact their citizenship while not affecting their ethnicty.
Furthermany of the ethnic Serbians in bosnia are for all intents and purposes Bosnians and Muslims. The Muslims, as was the case in all countries they invaded, proselytized through rape and forced marriages. So many of the decendants of these 'converts' live in Bosnia today, but are not culturaly nor religiously Serbian.
