NEW: Unearthed audio shows Dr. Oz saying incest is "not a big problem" as long as "you're more than a first cousin away." He added his daughters don't want to have sex with him because "my daughters hate my smell... Girls don't like their fathers' smell."
Dr. Oz on Incest: More Than First Cousin? 'Not a Big Problem.'
Yeah cousin marriage only became a taboo during the eugenics movement when the eugenicists vastly oversold the risk of genetic illnesses. It was completely normal and carried no stigma before that. It's still common in a lot of cultures.
