:::::::Yes, I'm talking about a Wikipedia rule (WP:Proper names). In your case your country of birth would be listed as SFR Yugoslavia. It's your privilege to think that this is a stupid rule and you might also want to take steps to change it (perhaps ask at Wikipedia talk:Proper names how such a rule can be changed - I don't know exactly the proper way to do this). But discussing this here is surely the wrong place. My concern is just to reach a degree of uniformity in the articles, whatever the rule in detail says.
