Dear South Croatian-Serb,
Im sorry to inform you but the word SLAVE comes from the word SLAV (our people), because Germanic tribes used to steal our people, or rather kidnap them, around 6-7 century AD and use them as SLAVES. It was so widespread that rest of Europe started using that word to describe slaves. Most of our people do not want to know this part of our history, including my mum. It is always the bloody Germans. This has nothing to do with African-American slaves. This guy's Balkan genes, could mean he has a Slavic ancestor or native Balkan ancestor (Albanians). Croats and especially Serbs are mix of ancient Balkan, Slavic and Turkic genes. Haplogroup I is definately not Slavic. Slavic haplogroup is R1a1. Thank you!
