It may not affect you or me personally, but it affects the women involved, the children involved, and society in general. It's a bad idea for our current society, which is why it's illegal. At one time it may have been necessary (say, in Biblical times). More wives = more children = more workers doing the grueling chores. But today's society doesn't operate that way.
We will have to agree to disagree, if someone is happy being wife number 8 of some guy, so be it...imo...la
It does not work that way any more. That is why a man and a woman have to both work and even then they are piling up tons of debt.
It is only illegal in some places. There is no law in most states that prevent cohabitation with two women any more. If there were then we would all see the hypocrisy of all the womaninzing men that want to fornicate and commit adultery instead of being right with two women
