Well, since the subject of hypotheticals has been breached, I can honestly say that if I could not inculcate in my kids a deep and abiding love for Christ (since a Calvinist believes that's ultimately in God's hands anyway), then I'd rather that they be atheist Objectivists, than to choose any other religion besides Christianity (preferably of the Calvinist sort).
With Christians I can share the Lord's Supper; but if they be not Christians, at least I can trust Objectivists with my Rights.
That's good enough for this world....
