Is it unthinkable that people could actually WANT a big family and ENJOY having lots of kids around?
And as someone else mentioned, the chances of these kids growing up to be anything but good, solid conservatives are slim to nil...so inspiring families like this one benefit all of us.
Based on the "Why would anyone want what I don't want" philosophy... Nobody needs more than seven kids. More than that and it's just a tribe. But seven's normal.
:-D
