Interesting: randomly found this in a journal of mine from 2014, yet it was similar to a thought that came to me few days before I stumbled across it:

"An attack on marrying multiple wives is an attack on marriage just as an attack on having multiple children is an attack on having children."

What I thought of before I found the note was of referring to the Roman laws that were made against multiple wives as "anti-marriage", "marriage restriction", and such like.
