I'm contemplating Al's tweet. And even without his previous theology about "quivers full" the idea that being "human" and being a "parent" are connected is a pretty poor drive by tweet.
I tried to think of how many people I've known in churches over the years have suffered because they couldn't have children. Or persons I've ministered with who were not able to have as many children as they wanted do to medical issues. Or, persons who never married and thus chose never to have children.
I know these short statements are a function of twitter. But why would you tweet something that would imply that persons who don't/can't/won't have children are not fully human? It sounds more like Mormon theology that Baptist theology.
