“A person with emunah does not “need” his child to keep shabbos.”
Shabbos is not a light thing like a bookworm staying up late, so I don’t think it’s a lack of emuna, or a sign of ego for a parent to do whatever it takes to prevent its desecration. But this assumption that hitting is somehow a universal power tool of parenting is dangerously incorrect. Klugeryid may think that we can dispense Hashem’s justice like Hashem does, but we are not the Master of the universe, and it’s far more likely that we’ll engender fear and hatred, not fear and awe. And what he describes in his scenario isn’t even Hashem’s way of disciplining – otherwise we’d all be dead and the world a barren wasteland.
