This meme ignores a ton of nuance, as there are many who publicly appeared to support the Nazis but worked behind the scenes to stop Hitler or save people's lives.
Schindler, Hosenfeld, and likely tens of thousands of Germans whose names will never be remembered (because many couldn't safely use their real names) but whose stories survive because of their bravery.
While I agree that people should publicly oppose authoritarian regimes where you can, it's not always possible to do when you live within a totalitarian structure.
