Okay. Picture three/four/five way divorces and property and custody battles. The only real legal protection that women have are laws. Against bigamy. “honey, I’m home! Here’s our new Wife! Don’t like it, want a divorce? Well, we’ll split the retirement three ways...”
Imagine a group marriage where the two biological parents are voted out but the kids have to stay by majority rule.
One way to address that is via the law. Meaning a couple would BOTH have to marry a new partner to the marriage.
Oh, and with bigamy laws voided you could have a man married to a woman and that woman married to another woman.
The combinations and complexities boggle the mind.
I suppose that’s why stuff like this is called ‘Pandora’s Box’.
Brave new world we have, isn’t it?
