I think it's safe to say most doctors and sociologists are against Polygamy for good reasons.
Rights are not subject to the approval of sociologists and doctors. Rights are
a priori, something every person is due by the very virtue of being a person -- I think Jefferson is pretty eloquent here, and straight forward.
(Besides, history is replete with examples of when said professionals were dead wrong -- I wouldn't want to listen to them on eugenics in the 1920s, for instance. Compulsory sterilization? Talk about disrespect for rights. I believe it's an error to think that they couldn't offer similar misguided judgments today.)
In any event, assuming a that marriage has anything to do with love is quite the assumption, and rather ahistorical. In fact, "romantic marriage" is quite recent. Even today, there are plenty of loveless marriages: shot-gun weddings, arranged marriages, green-card weddings, hell, even drunken Vegas weddings. In the past, marriage was primarily an economic institution; it had to do with property rights, not with love. In fact, today, some of the prime arguments for marriage equality are the property rights: taxes, survivor benefits, medical insurance, etc. My point here is that it doesn't matter whether the people are in love or not, nor does it matter if someone doesn't understand, or approve of, that love.
My view is that,
as far as government is concerned, marriage is a contract between consenting, competent adults, and generally speaking I think people should be able to enter into any kind of contract they want.
But -- I have a few concerns. Will all the partners be married to each other? Or could there be another arrangement? I mean, could you have A married to B who's married to C, but A and C are not married? Add any more partners and you'd have a very complicated legal arrangement that directly pertains to the rights I talked about above; does everyone inherit collectively? Who makes medical decisions (if it's done by committee, that seems to undermine the whole point of that particular right)? How would taxes work? What if one jurisdiction recognizes such a marriage (as state, say) while another does not (like the feds)? I know many gay couples are now dealing with that last one. So if someone could be legally married yet not have those rights we are discussing (that are, legally speaking, the heart and soul of marriage), I can see opposition on those grounds.
It is neither arbitrary, subject to my own feelings, intuition, nor anything like it.
Really? I don't mean to doubt your veracity,
JockBoy87; but then again, in your previous posts in this thread, how do you account for your liberal use of
exclamation points?!?!? That looks pretty emotional to me. But if it's a stylistic choice, well, I'm sorry, that's just plain gauche.
Plus, while in theory, the choice of plural marriage may not be any different to single partner marriage or gay marriage, the reality, as I see it at least, is that it's profoundly misogynistic and all part of the dominant male, servant-master crap.
That too is an assumption that is flawed. You are talking about polygyny, i.e., single husband, multiple wives. You are neglecting polyandry, which is one wife, multiple husbands, as well as the other possible permutations, like a wholly male or female group, or two men and two women, and so on.
