You‘re kinda misrepresenting the article. The author/interviewee is not for unlimited speech, she just argues that it should be private organisations doing the censoring rather than the government. (Which quite frankly, I find even scarier - Facebook can‘t be voted out of power within the next four years.)

However the Weimar Republic was extremely politically weak and refused to enforce them.

From the link:

>There were dozens of prosecutions, including successful prosecutions, against Nazis — including Julius Streicher, the publisher of Der Sturmer. And it just became a propaganda platform for the Nazis. It got all kinds of attention they otherwise would not have received, and sympathy they otherwise would not have received.

Against minor players, with little public support, they were fearful of doing anything against Hitler or people like Ernst Röhm.
