That is a pretty daring statement considering Germany just passed far-reaching anti-hate speech legislation with no precise definition of what hate-speech is, leaving it to social networks to interpret.
(FWIW, I see many problems with that law and it should never have passed but there is so much misinformation being spread that it gets tiring to correct.)

Just check 'verabschiedetes gesetz'.
Here are the full four pages of the law as passed: https://www.bmjv.de/SharedDocs/Gesetzgebungsverfahren/Dokume... and this is an English translation: https://www.bmjv.de/SharedDocs/Gesetzgebungsverfahren/Dokume...
