It's none of anyone's business what consenting adults do with each other, so you don't like what they do SO WHAT? If we made laws based on what people don't like nothing would be allowed.
If all persons involved are consenting and no one is being intentionally harmed then there is no valid reason to outlaw polygamy
"Polygamy" is not limited to polygyny. What exactly would be the harm in letting three women marry? In most places, it is entirely legal to live with, and raise children with, more than one partner, but not to be legally married to more than one at the same time. What sense does that make? Under a system of gender equality, there is no good reason to deny that we must keep evolving until an adult, regardless of gender, sexual orientation, monogamy or polyamory, race, or religion is free to share love, sex, residence, and marriage (and any of those without the others) with any and all consenting adults. Polyamory, polygamy, open relationships are not for everyone, but they are for some. The limited same-gender freedom to marry is a great and historic step, but is NOT full marriage equality, because equality "just for some" is not equality. Let's stand up for EVERY ADULT'S right to marry the person(s) they love. All the paperwork issues can be resolved.
People who are in support of polygamy just answer one question: How would the property and kids would be distributed when the marriage is broken.And watching your western trend where you people are unable to carry a simple traditional marriage how would you justify that in this marriage idea you would survive where there is more conflicts of ideas.World does not run on consent of adults,it runs on judgment of adults who can predict high success rate of future even when there is denial of consent.How dumb the polygamy supporters have become who claim about consent.300 million people in US so lets make 300 million laws serving consent of everyone. That's not how world works! A law is passed which force people to suppress their basic animal instinct for a better place.Acting like an animal does not make you normal.Western has the best infrastructure,health-care and everything in the world but they are the highest consumers of drugs like anti-depressant. You people have failed yourself in sustaining a normal marriage of two people and claiming about consent for polygamy.You dieing ,your kids are becoming dumber by every day when compared to asian or Indian kids.If you don't learn something now you are soon to be doomed with muslims and other immigrants shaging your cuck attitude in your face.
