What if 3 brothers (with the same parents) wish to enter into a polygamous marriage with each other?

Yes in every case.

Marriage requires two and only two eligible partners because its purpose is to create a stable relationship for bringing up children in a mating relationship. An eligible partner must be one person, unmarried, consenting, an adult, not a close relative, and of the complementary sex.

Where this whole business really gets silly is in validating all the other eligibility requirements--one person, unmarried, consenting, an adult, not a close relative--and rejecting sexual complementarity, which enables a mating relationship.

If marriage is not about mating, why restrict the partners to one person, unmarried, consenting, an adult, and not a close relative? If marriage is just about "love," people could certainly love more than one person, married or unmarried, consenting or indifferent, an adult or a child, a nonrelative or a close relative. It is only because marriage is a mating relationship that we recognize that some potential partners are ineligible because they are inappropriate as mates.

Actually, there is a societial/health reason for not allowing it. The more differing couples produce children, the less likely you are to be affected, as a group, by genetic disease. This is why people don't reproduce asexually. Say a man can get married to any number of women. He is rich and good looking, and all told he marries 100 women, and bears 200 children. Those children bread other children and so forth. If that first man had some undectable genetic disease or genetic deficiency, the portion of the population that was infected would be exponentially higher in this case then in monagomous marriage.

Very good question.

You have posted a thoroughly logical challenge to the "gay marriage" advocates out there -- and you know they don't like that.

So, if you haven't already done so, be prepared for accusations that you are "homophobic" and "hateful." That's what "they" say about anyone who ever dares question "gay marriage."

Never in my life have I seen a MAJORITY opinion be seen as "hateful" and "bigoted."

.

So, when straight marriage was codified in law, did people get all upset about the possibility that siblings of the opposite sex might want to get married? Did they say marriage shouldn't be allowed because that might happen? Of course not.

well, right now with marriage having a divorce rate of about 50%, id say it already has become a somewhat meaningless title

And what if the three brothers want to include their goat??

Who is to say what does or does not constitute "marriage"??

Is it consensual?

Is it harmless to them and to others?

If the answers to both those questions are yes, then I say let them bloody well do it. Why the heck not?
