Do you not have history classes in Ukraine? He was born and raised in Slovakia. He might have a hungarian blood line sure, considering the way the country was devided up in the 1920's it's likely sure. When he gives interviews and they say best slovakian cs go player he doesnt correct them saying oh no i'm hungarian lol. In most parts of slovakia they teach Hungarian in school sincr well... Part of slovakia was part of Hungary before the 1920's. Europeens have the most complex history of ethnicity than any other continent in the world as they are so close together, immigration is huge. My great grand parents were Irish they came to Canada at about that same time period, do I consider myself Irish or Canadian? Your ancestry doesn't determine your nationality, your passport does, his passport says Slovakia. You really need to grow yourself your own brain cells here.
