And there it is. Yes, that stance is awful. Going back implies removing the right of women to choose who they partner with. Enforced monogamy removes the ability of folks to choose how many partners they have. And who gets to define 'monogamy' and who does the enforcement?

It also completely ignores the poly folks out there, or the folks who are not interested in long term relationships.

It's at best, a narrow and puritanical view of human sexuality.
