And what if people wanted to marry their cats?
If the cats can consent to the act, then why not????
Hypotheticals aren't really helpful here, because who knows. You need to offer evidence that society stands to gain from polygamy.
Why? This is not done with other forms of marriage. Go ahead and bring up any existing type of marriage, make your best case for how wonderfully helpful it is to society and I'll be happy to bring other facts to the table of how both the individual contracts have negative perceptions and/or societal rates of divorce and legal issues.
Give me concrete arguments. Why should we change?
Because some consenting adults wish to enter into such a contract. That really ought to be reason enough as discrimination against this means it could conceivably be an ongoing issue of discrimination against adults who are able to consent to such an arrangement.
What will the benefits be? It's like with gay marriage, you can make clear and convincing arguments that gay marriage is a positive for society and so society had much to gain from legalizing it and attempting to normalize monogamy among LGB people. What are the possible benefits for society with polygamy? How will it effect society? How will it effect power disparities between the sexes? How will it effect children and inheritance?
Don't give me some idealistic "personal liberty" argument. That's not good enough, especially with the dire picture that studies paint of polygamous societies.
I think the personal liberty of consenting adults is reason enough. I think the negative items associated with any form of marriage currently outweighs the benefits, but that this won't matter to anyone that wishes to be married.
When I look at any articles / rational for "benefits of marriage" it really isn't making a case for monogamy. I think that is implied. On quick search for writing this post, I found sites that were explicit (though I wouldn't say over the top) about marriage being - between one man and one woman. Thus, not necessarily assuming this would include SSM. I think the points that were raised do include SSM. But also could include polygamy.
Your point is the negatives and that's it. I see that could, easily, be done with any form of marriage, and I really do think the negatives do outweigh the benefits, but also think as long as consenting adults want that arrangement, it'll be very challenging for it to not be a legal right in society, or to undo that as a legal right.
But since you'll likely come back with "I need the benefits" type argument, I'll list benefits of marriage as listed from a few websites and say that I see this applying to polygamous relationships as well as any other form of marriage. I could list the rationale applied for each of these and just substitute the form of relationship with polygamy as the points under each aren't really really concerned with the particular form. I would certainly challenge anyone who thinks that is the case and feels they can make that argument.

Honestly, as a B in the LGBT thing, I see anti-polygamy as having inherent discrimination against B, and essentially confirming bias that mono sexual activity is 'inherently right.' Sure, B's are able to get married to any gender they desire at this point in history. But if B wishes to marry one (or more) of each gender and all parties are in agreement / concept to such an arrangement, then what is the problem for society with this?
