I'm actually german and I do not agree with those laws at all. I'm not even affected by them, I just happen to think that free and unrestricted speech is most important and should apply to everyone and anyone, regardless of what is being said. Private law is a different matter though.
If the speech Facebook is forced to delete is illegal, there must be criminal investigation, by law. So it can't be illegal, which means the government is actually suppressing freedom of speech.
> Restricting hate speech and symbols is completely legal
"But it is legal" is not exactly a helpful response to criticism of a law.
