I grew up moving a lot. Most of my friends have not had similar beliefs to my own. I think I've maybe had three close LDS friends growing up. Most of my friends have been Catholic, agnostic, or atheist. I had a good muslim friend, she was cute. My mom's best friend is baptist, and I met a baptist girl recently who we share a lot of similar interests so I hope we can be friends. I think any break-off of friendships due to theological disagreements is wrong. Whether someone believes in trinity or not, whether they believe in polygamy or not. My sister says that she would be friends with anyone who isn't determined to commit and promote the sins God destroyed nations for, and I think that's a safe bet. Joseph Smith allowed preachers from other denominations to preach at his pulpit and welcomed them.
Just to add my two cents and not to argue, I love Joseph Smith on my own testimony so my being LDS won't change, but I know not everything I grew up with learning and my traditions is true so once again I like to hear what people say and am open to the fact that not everything I think I know is correct.
I don't know much about FLDS people, I tried to meet some, but I know there are a lot of crazy people who are cruel to them so they are very cautious, but because of that I can't say I know too much about what they actually believe. From what I can tell though, I don't agree with a lot of their doctrines or the way most of them live polygamy. But I would still like to be friends with them
Personally I believe polygamy itself (Why does everyone here say polygyny? What's the reason? I never heard that term till this site) is much more natural than monogamy. I know traditionally we grew up with monogamy so that is what everyone is comfortable with, but polygamy opens up a lot more things. And just because I believe that does not mean I look down on anyone who doesn't. And I definitely don't look down on people who have only one wife. Why would I? I just think it's a principle that if lived perfectly would be much nicer than a normal monogamous relationship, but as we are not perfect and are fighting our own traditions I think it is probably pretty hard and a lot of work but worth it
As for things polygamy opens to girls is the chance for closer friendships and ties. Pretty much every girl I know has a tendency to fan over boys. When we are younger in school the girls love to pick a boy that they all like and talk about how manly and handsome he is, or how funny and "Oh my gosh he said 'Hi!' to me today!" Then as you get older you are afraid because you can't all marry the same man so jealousies ensue and girls are forced to pick different guys than their friends to like and pursue. So I want to marry a man with another wife who I can giggle over, talk about how handsome he is and talk about our different romance stories with him, because love is love. And if you marry a man who you love and who loves you you are going to have a story about it. Jealousies do happen as we are not perfect but you know that's never going to change whether you're in a polygamous relationship or not. I don't think there's a married woman I know, and I personally only know monogamous women, who doesn't complain over some jealousy or another.
Another polygamy helps with is the physical differences between men and women. I grew up hearing women complain about men's sex drive. Men from what I can tell and have heard have a much greater drive. They don't need a break every month, and they don't get pregnant, so from what I can tell, a relationship with one many and a few wives is beneficial for both genders.
I'm sure there are more reasons and maybe one day when I get married I'll make a list for you all. I know I know, I am not in a polygamous relationship nor do I personally know anyone who is, so my opinions are not perfect but I don't think being in a relationship leaves you with a perfect knowledge either.
Frankly I think any complaints about polygamy lie with people not being perfect and not the basic principle itself.
