Godwin ?

I don't care, it's still a good point:

The problem is, the Weimar Republic had [hate speech laws]. It used them freely against the Nazis. Far from stopping Hitler, they only made his day when he became Chancellor. They enabled Hitler to confront Social Democratic Party chairman Otto Wels, who stood up in the Reichstag to protest Nazi suspension of civil liberties, with a quotation from the poet Friedrich Schiller:

"'Late you come, but still you come,'" Hitler pointed at the hapless deputy. "You should have recognized the value of criticism during the years we were in opposition [when] our press was forbidden, our meetings were forbidden, and we were forbidden to speak for years on end."

The Nazis would have been just as repressive without this excuse, but being able to offer it made Hitler's task easier. Like Canadian supporters of hate-speech legislation, supporters of the Weimar Republic thought that their groups and causes would occupy all seats of authority and set all social and legal agendas forever. Shades of the Canadian Civil Liberties Association or the Canadian Jewish Congress! They couldn't envisage the guns of their own laws being turned around to point at them one day.
