I take the position similarly to, like... child abuse for instance. I mean, nowadays it can be interpreted or is "redefined" as a light spanking for crying out loud and kids can actually call the freaking police on their parents. ??? With marriage, I take more of a historical view, but not that it's better. But it's has worked! The definition of marriage has never changed, but the interpretation to amend it has. Traditionally, it only included those of the opposite sex, that hasn't changed. People have simply added to it to include same sex persons.
