Robert Habeck was NOT arrested, he and his friends were investigated in the broader case of neo-nazi propaganda which they were spreading as well. Unless you consider neo-nazi freedom of speech, of course.
The Pinocchio case meant exactly one official letter sent to that guy, lol "arrests". The investigation was dropped and everybody criticized the investigation.
Ricarda Lang case was a request to the well-known network Gab to identify who insulted the politician, because in Germany insults are a crime. Maybe in the US insulting is a popular free speech pastime, but this is not US. Gab refused to identify the person and that was that.
So, again, I can see when we are spreading lies to support some ideology, but they are just that: lies.
