You got that wrong mate.

Third step: Broaden the definition of nazi and repeat.

Fourth step: when they came for me there was no one left to speak up.

No. They came for the nazis. There is no slope from nazis to good people.

There is no objective definition of good. To someone you're a good person. To someone else you're as bad as a nazi. That's the real slippery slope: from benevolent censor to malevolent.

I don't murder people, so...no. That is incorrect. Someone can say I'm as bad as a nazi, but they would be incorrect, so their opinion would not matter.

So murder is the limit? But not all nazis murdered people.

The nazis killed many philosophers. I wish you luck.

I disagree.

If you had your own website where choices of this kind need to be made.. sure, you can go ahead and make determinations based on principle. Your own definitions and evaluations of Nazism, evil, eviler and such will shine through, especially the priority list. Your own values will shine through the "what worked?" Step. Overall though, it would be totally fine. You are a person (presumably a decent one) and your principled choices are a great way to govern your website.

YouTube is a major part of global media, a major subsidiary of Google/alphabet and a major channel through which democratic politics, speech and social life is conducted around the world. YouTube makes more mayors, parliamentarians an public intellectuals than they likely even bother to know about.

It's an institution, in every sense. Ways of doing things that are perfectly workable for a person do not translate to institutional scale.
