Most people would check that box, as apparently they did. I just called my mom to ask and she confirms this, although agnostic at the time, she feels confident she would have checked such a box. All the emphasis is in the word 'moral'.

Now you say 'every single person you've met' yet if you'd looked through these replies, you'd see that none of us who have homeschooled or been homeschooled have said that was the reason. Perhaps for some it was, but we have multiple comments from people on this thread explicitly stating that it was not a factor.
