Polygamy - 

the practice or custom of having more than one wife and/or husband at the same time.

Polyamory - 

the philosophy or state of being in love or romantically involved with more than one person at the same time.

I wouldn't do it, but 3 consenting adults can have any type of relationship they please as long as it's not harming anyone else.

So it's fine for me if someone wants 2 wifes, or 2 husbands, it's their business.

TBH, i think someones else relationships if they are all fine with it shouldnt be messed with, why should we care? Let them be happy :)

If I don't vote that I support both I am pretty sure my wives would kill me.

I have always found the idea of restricting yourself to one emotional bond to be an unnecessary self-set limitation. So long as everyone involved consents and can handle sometimes prickly situations in a mature manner then there isn't any harm in having a poly lifestyle.

As far as I'm concerned they can have a huge tangled family tree of intersecting wives, husbands and sexualities as long as everyone involved is a consenting adult doing this out of their own free will.

Not for me personally though, I couldn't keep up with so many people romantically. :P

A while back I was reading the book "The Moon is a Harsh Mistress" by Robert Heinlein for probably the third time. In that book there is a particularly interesting group marriage (which also was a line marriage I think) that had a head husband and a head wife. I was trying to explain it to two of my friends who are gay (like myself) and they just blew polygamy off as patriarchs marrying young girls and that it could never work out and we should not associate with polygamists NOR polyamorists. I've since asked many people gay, straight, bisexual, etc alike and they also have similar opinions on it. It didn't matter if they were religions or irreligious, they hold said beliefs. Its interesting seeing the responses here are so positive. I see myself living a very single life, but I can also see myself in a polygamous group marriage where you have the freedom expressed in The Moon is a Harsh Mistress. It just baffles me how people who are part of groups that were told they couldn't marry or discriminated against because of their relationship choices feel like they should do that to others, most of all.

Polygamy is something I personally don't support.

Polyamory on the other hand isn't anything too foreign or unusual, IMO.

Lot of people here are willing to speak up because they are anonymous. I've seen stuff like you are describing irl.

I mostly like the notion of 1 man 1 women but hey, if everyone agrees to the haremfest that is Polygamy and Polyamory, then be my guest cause I sure don't got any issues with that

I feel like people for the most part always view situations they aren't involved in with a very high level of disassociation.  Especially when it comes to love/sexuality etc.  It is easy to look at something and say "not for me, shouldn't happen" and move on.  To actually try to put yourself in that situation can be uncomfortable, and that can breed unnecessary discrimination.

Society itself has pushed the idea of monogamy for so long it is very hard to break from the pack regardless of your own sexual preferences.  Thing is, it is natural to see two different individuals and feel emotion toward them to some degree.  It's not like we have switches in our heads that can turn off the idea of being attracted to people just because we have someone stable in our worlds.  For that reason I see the poly lifestyle as more natural than a mono one.
