Since you clearly are offended, I'll let you continue to think it over some more Krinkled. You can be offended all you want to, and I don't really care if I offend people in open relationships either, at least not on a Christianity Forum, where it is a sin. If you think sin is okay, and you are offended by me calling it wrong, be my guest, but you can't justify it. I'm sorry, but you're wrong.
You can call it whatever you want, and you can claim whatever you want about how much your friends "love" each other in their open relationship, but let's just call it what it is, shall we? You're friends have sex with other people, cheating on each other nonstop, while still claiming to be in a relationship full of love. What a joke. Also, are you seriously trying to justify a sin on a Christianity forum, and then saying that I'm rude for calling it a sin? You're friends are disrespecting themselves and their partners. What happens if the girl gets pregnant from one of the many guys she sleeps around with, and the guy gets an STD from one of the many women he sleeps with? Does he still stay with her, and her with him? I bet you they don't. Oh, but open relationships are good.... because relationships are about sex and not about future marriage... right??????..............................
Anyway, God created Adam and then Eve. He didn't create Adam, Eve, and Steve. He didn't create Adam, Eve, and Lilith, nor did He create Adam, Eve, Lilith, Jessica, Jennifer, Jenn, Joanna, Jacinda, and a future wife to be named later.
If you don't like the Bible or what it says, that's fine, but don't argue it being a "right" thing to do on a CHRISTIANITY forum, when the bible clearly states it is wrong. Since I highly doubt that most polygamists simply marry their brother's widow, and since times are different now to where women can support themselves independantly, I don't think you have much to stand on here.
