[IANAL] In Germany only specific types of hate speech are criminal. These are:

• Use of Nazi symbols and slogans for other than artistic or educational purposes (things like the Swastika, the SS logo, or the Nazi salute, but not more modern versions like the "white power" guesture and similar)
• Direct calls for violence against groups or individuals
• Denying that the Holocaust happened or trivializing it's extend

Other forms of hate speech might be cause for civil suits or may oblige the platform provider to remove your speech, but do not rise to a criminal offence.
