Insults are a crime in Germany.
Keep in mind that someone actually has to go sue for that, it's usually not automatic, unless you do it right in front of a police officer trying to insult some public figure. In front of court it's weighed against freedom of expression. So there are plenty of examples were the "insult" becomes a "matter of fact". Like for example the matter of fact that AfD politician Bernd Höcke is a Nazi.
