Minor point...
Polygyny - - one man many wives.
Polyandry - - one woman many husbands.
Polygamy - - any combination thereof, including homosexuality and pederasty.
The main issue (I do agree with the general arguments of the article) I see is the ongoing, perpetual struggle between the forces of Paganism and the Judaic.
This violent struggle from the very beginning of human history is manifested, only in part, by sexuality...
Pagan Babylon, pagan Egypt, pagan Greece, pagan Rome, pagan Islam, pagan National Socialism, pagan Marxism, pagan neo-Islam (once again), and modern neo-pagan New Agers.
Mosaic Law is the foundation of Western Civilization, it is something that neither the pagan Islamic thugs or the neo-pagan Left can abide and seek to destroy... they both seem to be on the same side, don't they?
No, it is the Law of New Testament combined with the learning of the Greeks and statecraft of the Romans which is the foundation of Western Civilization. Give me one example where the Mosaic Law took precedence before Christian doctrine. Not in the case of poligamy!
