The only “self selecting” going on in this “statistical pool” is being done by parents who actually care about their children getting a good education and a good founding in character principles based on the Truth as revealed by God.

Do you know what "self selected" means? It doesn't mean weird, and it's not a criticism. In fact, your description of the parents neatly sums up why their kids are "self selected" in any kind of survey of education.

Yes, I do indeed know what “self selecting set” means.
Don’t go all “I’m an atheist so I’m smarter than everyone else” on us.
