I mean, we also have freedom of speech here in Germany. There are (harsh) limitations around hate speech and insults but besides that you can say what you want.
What’s also a definite no are nazi symbols. Swastikas, SS runes, nazi salutes, etc. are only ever allowed in the context of education and art (like period films and as of fairly recently, games).
We also still do have regular day to day nazis in Germany and sadly the far right party AfD has been growing in numbers over the last few years, taking a lot of inspiration from US republicans in their talking points and rhetoric. Since July they are in a county government for the first time, having only ever been an opposition party until then.
Germany wasn’t built on the principles of freedom (of speech) but that human dignity is inviolable. That’s Art. 1 of our constitution. Only Art. 2 then defines personal freedom.
