"Pre-born children?"  Don't you mean pre-dead children? I mean, we're all gonna die.  And what about all those pre-born sperm and ova? Aren't you concerned about them?

When will idiots keep their noses out of other people's private business and shut their big, stupid mouths about private matters that don't concern them?

They're smarter than human religious nuts and anti-abortion zealots.
