I see no difference between polygamy and polyandry.
Do you actually believe that women in “polygamous” marriages don’t get jealous and hate the other wives?
As I wrote above, the big difference historically was the children knew who their parents were. It was also very practical in a warrior/tribal society where a lot of men were killed in battle. It was an efficient way to take care of young widows and orphans and replenish the numbers of the tribe.
Well, I don't know. But I do know that polygamy has existed since forever, and that there have been many stable and long-lasting civilizations that practiced polygamy, whereas there have never, ever been any successful cultures that practiced polyandry.
I presume the reason for this is that men and women are radically and fundamentally different from each other.
Only when it’s HER turn to clean the commodes!
