Calling Mussolini a "great leader" isn't just immoral. It's also clearly incorrect for any reasonable definition of a great leader: he was in the losing side of a big war, if he won his ally would've backstabbed him, he failed to suppress internal resistance, the resistance got rid of him, his regime effectively died with him, with Italy becoming a democratic republic, the country was poorer due to the war... all that fascist babble about unity, expansion, order? He failed at it, hard.

On-topic: I believe that the main solution proposed by the article is unviable, as those large "language" models have a hard time sorting out deontic statements (opinion, advice, etc.) from epistemic statements. (Some people have it too, I'm aware.) At most they'd phrase opinions as if they were epistemic statements.

And the self-contradiction won't go away, at least not for LLMs. They don't model any sort of conceptualisation. They're also damn shitty at taking context into account, creating more contradictions out of nowhere because of that.
