I'm sorry but gay marriage should never be added..
You can call it freedom of choice but it means you don't need a law.
If you love a guy, that's a best friend, not a fiance. Guy isn't a replacement for a girl. They're guy, and they shouldn't be a sexually attracted opponent. Or at least, they shouldn't be publicized like you want because people, especially young ones will learn a wrong thing through that.
I'm not saying I'm not a weirdo and only the gay people are weird. However, people shouldn't try to make weirdo utopia. If they're doing weird stuff, they do it alone. If it's not right, you shouldn't make it right.
