UH, newsflash, Iranians ARE the same "tribe" as we are, that explains the "sexual connection". As well as Women from Northern India. It is religion that has seperated us not race. A long time ago, circa ~4000BC there was a tribe, scientitsts dont know what their name is (they had no writing) that lived a "horse culture" in the plains of Asia. They migrated to Turkey through the "CAUCASUS" mountains, Hence our name "caucasian". They are refered to in Literature as the "Indo-europeans" In turkey they split up going east into iran and india and west in Europe, hence "INDO_EURO-pean", Both the Egyptians AND babylonians recorded their arrival from Asia (ME WHITEY FROM ASIA? ME SO HORNEY!)
Eventually we became Christian and they Muslim and hindu but we have the same close DNA. In fact 'Iran' in Farsi means 'Aryan' and thier symbol of luck was the swasticka.
Hitler ripped off that idea from them because he belived they were ancestors of the "true" white people, which they were. Hey, the more you know!
