They seem a little, well, weird and unsocial. Perhaps an FLDS sect? I’ll call it the “J FLDS Sect.” It’s great that they love having kids but something is a little off.
And just what are you basing your judgement of “weird and unsocial” on?
No, they are a Christian family. And their social skills, from what I’ve been able to discern, are more advanced than average kids.
If you’ve read the bible, you’ll conclude that large families are not in the least unusual.
