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.
There are always lots of men who cannot get laid.
If a wise man can and will support 300 wives and 600 concubines the burden on society is lessened.
Probably he should nominates for sainthood too.
