A group of upstanding young people from Utah recently held a rally in support of polygamy. The kids were themselves the fruits of polygamous loins, and were defending the practice as an important aspect of their families' religious beliefs.
It must be good to know, as a young person, that God will reward your steadfast abstinence later in life with multiple mates (maybe this Mormonism thing is worth looking into after all) and oodles of children. Orrin Hatch, you dirty old dog!
Seriously, can you imagine this: "Not tonight, you have a headache? Next!" "Having your 'monthly visitor?' Next!!!"
What convinces me that polygamy is bullshit is that, like so many other aspects of religion, it's gender-biased. A man is permitted to have multiple wives, whereas women are only allowed to be a face in the conjugal crowd.
There will be no divinely sanctioned sausage-fest for you ladies, I'm afraid. But the hubby gets to have him a harem. (Say that 10 times fast.)
Clearly, polygamy is not heaven-sent, but man-made.
