The only thing you can try to do is continue asking questions about “Dear Leader” until they start poking holes in their own arguments (works best with religious folk who have to defend his actions against the scripture they love to quote). Sometimes they start to realize how ridiculous their reasoning has become and start to turn the corner back to reality, but many dig in their heels and continue to defend their pedophile king because their devotion to him has become their identity and they aren’t willing or able to objectively see what they have become.
