Personally, I wish we'd use different terminology for one to make things more clear. Say, two adults who wish to be recognized as spouses by the government enter a civil union, conferring on them the same legal benefits currently allotted to married couples. No ceremony necessary. If two adults want to have a religious ceremony to recognize their union, that's a matter between them and their respective church. No legal obligation required. I'd much rather see the split be between 'legal benefits' and 'religious rite', than giving a different term based on the genders of the couple.

The reason for this is to (try to) ensure equality. In some religions, one partner is inherently dominant over the other. A legal framework protects the other partner. It also avoids polygamy.
Now on the issue of marriage between more than two partners. I believe that in a marriage, all partners should always be equal. In my opinion, equality is only possible between two individuals. In a group of three, inequality is, in my opinion, almost
