This is false. German anti-Nazi laws are weaker today than under Weimar and the society is generally much more liberal.

Of course the reason why no nation has renazified is because Fascism exists as a boogeyman of the left rather than a reality. It is a completely discredited ideology. If you look at every public opinion survey, there are many more communists than there are nazis, even though morally both sides are equally odious.

If you could find a Nazi lurking about somewhere, rather than in the nightmares of radicals, they would never say "Real Nazism has never been tried". Whereas there are actually people claiming to be communists and insisting that communism deserves a tenth or eleventh chance. Nazism is a completely defeated ideology even as communism continues to try to come back from the grave.

You don't need one article. Just a basic grasp of history. We in the "West" are today a more liberal society, especially with regards to speech, than ever in history. Stuff that would have gotten you locked up in 1920 will not get you locked up today. If you don't understand that, or question it, or seriously believe that there were more political freedoms in the 1920s rather than today, then God help whomever was your history teacher.
