Yes to "Domestic Partnership", done by a lawyer, not a priest.
Yes to adoption.
Homosexuality isn't a disease. It's a life choice. And not a bad one at that. It's just different. It's a mocker of civil liberties to not have equality based off sexual preferences too. We can't control who we love. And some "holy book" isn't the dictator of law. That's why there is a separation between church and state.
Personally, I don't even understand the opposition to why you wouldn't allow domestic partnership. If it's not done by a priest, it's none of your business. And who says homosexual's wouldn't make good parents? They go through more emotional hardships than anyone else right now. They can actually relate and help their children more than most can.
