As far as personal relationships...knock yourself out. Actual marriages, however?

Let me be blunt, NO. No, I don't support polyamory for any sort of legal privileges the way marriage does. It's difficult enough to have a marriage last with two people when there's only one relationship to worry about. Three people means three separate relationships, which means the whole affair is three times more complicated.

If our divorce rate was less than 1% and a third person did something other than spice up the bed, I might change my opinion, but with it close to 50%? I will be generous and assume that polyamory will have the same divorce rate--we all know jealousy will make it markedly higher, but let's ignore that. That's a 13% chance there won't be a divorce.

Let me rephrase that: if you have children, there's an 87% chance you will be giving them a highly stressful and potentially emotionally damaging experience. How is this not irresponsible and foolish?

Would the divorce rate automatically go up though? Even if we assume there would be more jealousy (which I'm not sure of, if somebody is going into a polygamy then they must already know they have a higher tolerance of jealousy) what about other reasons couples divorce like stress caused by raising kids/earning income? If three or more people pooled their resources together and made decisions, financial hardships might be fewer and less severe. Also such couples might be more thoughtful and create contracts that explain how everything splits up (maybe make it a requirement?) Honestly, I don't think marriage should mean benefits, and all people who want to get married and be identified as ONE by the state should be required to construct at least a basic contract explaining what happens upon divorce. That includes two persons or ten. 

I support polygamy only when it's allow by the Lord and given as a revelation. Polyamory on the hand I can't say I agree with but I can't judge anyone who does that. Everyone has free will and can do what they may.

I don't care if someone is into those or not. If they want to, go for it. Personally, I'm not into it. I prefer to date one woman simply because it's easier for me to focus on one woman versus trying to divide my affection/attention between multiple women.

I think you guys are mostly thinking about polyandry and polygyny. There can also be multiple husbands and wives whom you don't have sex with, but they have sex with each-other, but everyone helps take care of the family and has a familial love for everyone else.

I go near Taylorsville pretty much every day. I live in Sandy, work in South Salt Lake, and go to School in Taylorsville.

That's so weird, since my experience has been so different from yours. Many of my gay friends are in open relationships where they're emotionally committed to each other, but explore other partners sexually. Full consent between both parties exists and everyone seems like they're happy, at least on the surface. I guess it surprises me since I don't know anyone in a 3-way relationship, but I would think that the LGBT crowd would be open to polygamy/polyamory more readily than others. 

I think as long as everyone consents than live and let live. I don't claim to fully understand or identify with these concepts and I don't think I could ever be a part of a polygamous/polyamorous relationship, but that doesn't mean others can't. 

I personally don't care what other people do, if it makes them happy and isn't hurting anyone physically or emotionally. However, in my own personal life, any relationship I have would have to be monogamous, and I'm more than happy to be alone if that's too much to ask.

I support both. It's up to the individuals. That said, in the case of polygamy, all linked people should be present at the moment the (new) individuals are married.

Then we get to the definition of marriage, which I feel should be purely a cultural thing with no governmental or legal ties. Instead, I support registered relationships for all, and that should be the thing with possible legal ties. Problem solved, definition of marriage not altered!

Well I am kind of in a open-relationship right now. The person I'm with thinks of the other encounters he and I have mostly as sexual and friendly rather than romantic, and also holds such negative beliefs with regards to polyamory/polygamy (which we both agree requires romantic involvement with more than one.) I think most gays have similar beliefs, at least the ones I've spoken with. They can imagine having sex with multiple people at once, but not being romantically involved with multiple people at once, if that makes sense.
