In 5,000 years of recorded human history... neither in the east or in the west... has any society ever defined marriage as anything other than between men and women. Not one in 5000 years of recorded human history. That's an astounding fact and it isn't until the last 12 years or so that we have seen for the first time in recorded human history marriage defined as anything other than between men and between women.
