This means you would have been OK with Goebbels to carry on doing his stuff then.
A key difference under Goebbels is that there wasn't any other kind of speech allowed. The Nazis used violence and repression to silence any speech that would oppose them.
One thing I've noticed about the debate regarding hate speech is that much of it seems justified based on the (in my opinion) erroneous historical notion that the Nazis came to power solely through the power of speech.
As if the fact that people had to carry wheelbarrows full of money to the market to buy a loaf of bread had nothing to do with it. It was all due to speech, or so the argument implies. The powerful charisma of Hitler and his magical oratory - it's a common trope in modern historical perspectives of that era.
That position suggests that if hate speech had been banned in 1920s Germany, Hitler could never have captivated the German people and rose to power, which might have saved countless tens of millions of lives.
Based on that perception, the idea of banning hate speech seems like a no-brainer.
But it would be far more effective if they'd simply ban high prices and other forms of economic privation. When times are good and the people are happy, hate speech has very little effect.
It's not the speech. It's the conditions surrounding the speech. Make the conditions better, and you won't have to worry about the speech. Refuse to make the conditions better, and you might have to worry about speech.
