And then neo nazis go around telling susceptible people "Look, Hitler's detractors think he had 12 fingers, just look at any picture of him, he clearly only has 10. You're gonna trust people that stupid to be honest about him? To know anything about him?"

Disinformation feels good in the moment, but is immensely damaging overall. Even the people who believed he had 12 fingers will feel betrayed and question everything else when they one day learn he actually had 10.
