According to Dictionary.com, polyamory is the practice or condition of participating simultaneously in more than one serious romantic or sexual relationship with the knowledge and consent of all partners.
I have no problem accepting polyamory, even in lifetime partnerships, because I see nothing immoral in an act unless there's harm done to a victim, an innocent person. If the people involved are happy with it, that's fine with me. This is a general rule for me, of course, there will be exceptional cases of immoral acts that derive from any kind of relationship.
And on a related topic, I think it's morally wrong for the governments in the USA to give special rights to married couples. Marriage is a religious sacrament. Why is the government involved in promoting religion? Domestic agreements can handle the property issues when life partnerships are dissolved.
Your opinions?
The government exists to protect the Life, Liberty, and Happiness of its people.
As such, the government is not necessarily concerned with the 'morality' of actions. For example, the government may declare War. This does not automatically make war a moral action. The government is inclined to follow the Will of the People it governs. Those things that are in the best interests of its people are not necessarily moral things.
Anytime the government considers getting involved, it has to consider its duty to protect the Life, Liberty, and Happiness of its people.
If marriage is a religious sacrament, that does not mean that the government should not be involved.
The government shouldn't make laws establishing a religion or preventing the free exercise thereof.
Marriage has implications.
Who owns the house?
To whom do the children belong?
What about the grandmothers and grandfathers, the aunts and uncles?
This formalized relationship affects everyone.
You cannot simply say, "We don't care about the world, so why should the world care about us?"
It doesn't work that way. There are other lives at stake besides your own.
What if those involved just want the sex and don't care about marriage?
You think this is just about you? What if someone gets pregnant?
It's such a self-centered, ignorant view to think your actions don't affect others.
The morality of polyamory is irrelevant really. The religious significance of those relationships is equally inconsequential. The only real question is what are the rights of the people and how is the government protecting (or not protecting) those rights.
The question is not "Are these actions moral?"
The question is not, "Does marriage hold some religious significance?"
If someone wanted to revive the Aztec human sacrifice, the government shouldn't be stumbling over itself about not interfering because it's a 'religious' ceremony. It should be getting involved and protecting people's Lives. Freedom of Religion is not freedom to destroy the lives of others. That's not how this works...
