Even where Homosexual activity was either accepted or condoned Homosexual marriages where never allowed.
This is the logical consequence of the allowance of homosexual unions condoned by the State. It is inevitable that Marriage will now be ANY union of ANY set of adults that desire the political and economic benefits of the union. With today's welfare state and the increase in middle East and Muslim immigration it will soon be commonplace for a man to have three or four woman with dozens of children all benefiting from food stamps, welfare payments, and government housing subsidies.
Sorry. It was not "the norm." It wasn't in the Middle East, India or China; it tended to be practiced by rulers who simply did so 'cause they could. Yes, it existed more in pockets of Africa, but studies show that polygamy actually reduces the number of children per mom; and any generational implementation of polygamy would have only contributed to the eventual weakening of #s & eligible marriage partners in a given culture, with it eventually leading to tribesmen marrying closer & closer family members.
