What really cracks me up is the feminists who insist that marriage was invented by men to control women. I always say, "Oh? Is that why men are fighting so hard against the erosion of marriage and the advent of free love?" Marriage is one of the proofs of G-d's existence. Based on the physical strength of men and women's reliance on them before civilization, marriage would never have evolved on its own. Men would have controled women by saying, "You don't want to put out? Go sleep with the saber-toothed tigers."
Shalom.
LOL! But remember, that powerful men have an interest in controlling the (revolutionary) impulses of lesser men, and marriage is a good way to do that. The powerful men, of course, had large harems (just like Senators today) and didn't follow their own rules. ;)
