I have always been a proponent of polygamy.
Some years ago when the demands for gay marriage were fomenting on my state I demanded polygamy too.
I was horribly savaged and maligned by everyone on all sides.
The Republican party was founded on the twin principles of abolition of slavery, and the abolition of polygamy. What do you know, Americans who saw it in practice found that it resulted in conditions little better than slavery for the wives. Also, polygamy is very unhealthy for a society. Look to the Middle East when you have a whole region full of young men who can’t get laid. Polygamy winds up leaving some guys unable to find a mate. That leads to very bad results when it’s widespread.
