Normally I agree but Godwin's law is officially suspended the moment they threw a Nazi salute.

Regardless, Godwin's Law is a thought terminating cliche, which is shielding us from the truth. The person you responded to wasn't calling them Nazis (although I am), they were asking you to engage in a hypothetical to try to make sense of a problematic issue: for 70 years since the Holocaust we have heard the slogan "never again", as a cry to the future to prevent such an atrocity from ever happening again.

The question to all those who hear that cry is: how? How do you prevent a holocaust from happening again?

The problem the parent is pointing out is that the perpetrators of a holocaust don't say that is their intent. They will say they are "punishing criminals", "deporting illegals", "purging drug dealers", "cleaning up the streets", "bringing order", "causing peace", "uniting the nation", "restoring glory" etc.

Therefore in order to prevent a holocaust, one has to necessarily stand in the way of people who claim to be doing good. No one doing a holocaust claims to be doing evil.

If you wait for undeniable proof of a holocaust before you act to stop it, you will fail. That kind of proof only comes after the fog of war has cleared.

Therefore if you really want to prevent a holocaust, you have to do so before they consolidate power, before they operationalize their intent, at the stage when they still have plausible deniability, and when they can make their plans seem reasonable. You prevent them from laying the groundwork for the holocaust, despite all the deniers.
