When Horton Hears a Who, he declares to all who ridicule him for protecting a speck of dust! for cryin' out loud -
A person's a person, no matter how small!
Horton wasn't talking about the pre-born, was he???
Unfortunately, it appears not. I just did a Google search, and Wikkipedia, that dubious resource but a good starting point, reports that the good Dr Seuss and his widow both found the appropriation of such a very obvious comment to an "agenda" to be abhorrent.
Still, it's true - a person is a person, whether he's been born or not, or a child (the phrase could be used in the war against child abuse) - or how oddly big (Andre the Giant would have appreciated being treated like a regular person, I suspect) -
Why does it seem so difficult to grasp what ought to be an elementary-level truth? A person's a person....
