It hasn't been that long ago that we didn't need a written definition of "person" in every document to know what it meant. The whole concept of words not having any meaning is a very recent development.
Yep, marriage means ONE man and ONE woman, person means ANY PERSON, God means GOD, it’s amazing what we need to spell out these days. Some out there seem to think that because the Founding Fathers never said that it wasn’t okay to murder the unborn, the sick and the elderly that they must have been in favor of it.
