Can anyone name a single legitimate reason why polygamy is illegal?

Sure. So are women who aren't interested in sex or marriage at all. What of it? We are talking about more women removed. That some are already out doesn't address that.

No. If the ratios are off then there would be more of one gender in that situation. I think it would be more men.

I don't follow your logic here.

Sure. Units of people who are bold enough to buck the social taboos, which change with legal recognition. The numbers of homosexual couples went up when it was legally recognized. If the ratio of lesbian to gay male couples was very off, then this would have had the same issue.

I personally support gay as well as polygamous marriage, because I support freedom of people to choose, but I can understand the concern.

She has less choice if it's not legal. So she's more likely to pair off in monogamy even if that's not her top preference. Same goes for the men today would would like to have many wives and have women interested in it.

That's true. Gender ratios are not always balanced. China has more men than women. How this would effect society depends on the ratios as discussed above, and I don't know what they would be.

No. That we already have a problem doesn't change how much more of a problem we would have if we changed something.

 

Basically, there is nothing stopping men from entering into a polygamous marriage with multiple husbands and/or wives. The only way that this becomes a problem is for those who only want monogamy, or want multiple women with the "one dick rule", which is rather misogynistic to begin with.

Did more actually enter into dedicated relationships, or was it only a matter of those taking something from the social only realm to the legal realm as well? Do you have some kind of numbers to support that those who went out and got married after SSM was legal were not already married in all but law?

Based off of what? The only way that this happen is if the person in question does not want any paramours of the same sex as themselves. Or worse, can't accept a paramour of the opposite sex who doesn't want to be with them.

At the rate they're going China might have to accept polygamy in the form of polyandry. That is a form of polygamy that is practiced even today in other cultures in Asia

I am going to have to try to find some time to see what research is out there. This might have to get tabled until after the holidays. But as I noted, I'm not seeing this as a problem in the MidAtlantic region. The mix is varied and I see just as many units with multiple men not to mention all the non-binaries/transgenders out there. And that may be part of what keeps this from being so unbalanced. Many of the NB/TG out there are also poly, although by no means all. Plenty are monogamous as well. But given the openness of most polys there could be a lot coming from the NB/TG's that the otherwise straight cis men aren't going to want to touch to begin with. And again, I don't see a problem now. The closest is the incels, which are not really having a problem with a shortage of women, but a problem with themselves. And that is my point. Incels aside, if we were going to have a problem, then we would already see it now with people already living polygamous marriage in all but the law.
