Don’t mock them too much, this is coming to the US very soon. Homo marriage has opened Pandora’s box and polygamy will be the first thing out, most likely followed by a whole host of other things.
You are correct. Much whoopee will be made in certain “conservative” quarters.
Homosexual marriage did not open anything.
No fault divorce killed the baby.
Homosexual marriage, polygamy, polyandry, bestiality...all of those are just dirty bathwater.
Before no fault divorce, Homosexuals with extremely few exceptions wanted nothing to do with marriage. Because despite any posturing to the contrary they know they will be promiscuous and the financial consequences of that in a divorce was way to big a risk.
To fix things, focus on where society veared off course. Don’t try to be broken but in a lesser way.
