There is somebody here who is ignorant about marriage and it sure isn't the gays.
You sir, have no idea what you are talking about. Marriage ties two unrelated people's lives together, and short of spending tens of thousands of dollars in legal fees to create a patch work of documentation that provides some protection, there is nothing even close to it.
Don't even pretend to be open minded on this issue. I've met enough posturing posters to know one when I see one.
