Lol, that's not a first I've heard. But there's a reason why majority of the world population marry within their own ethnicity and how interracial couples are only popular in countries like America, Great Britain, and Australia (which nearly doesn't even make up 1/3 of the world population). Being raised in America (a melting pot of diverse races, ethnic groups, cultures, etc) allows one to be more open-minded with developing relationships with people outside of one's ethnicity.
