The only plurals I know are multi-husband communities and everyone involved are happier than clams. Your concern trolling to equate happy relationships with domestic abuse, simply because you don't understand them and think that everyone in a plural relationship is FLDS and lives in Utah, is pretty striking and antiprogressive (which is odd, considering you're attempting the progressive argument against their happiness).

And no, what you're saying is not "well known." You are arguing against certain fundamentalist groups, not plurals. They are not equivalent, despite this thread's clear goal to say otherwise.
