You can hate as much as you want, in private. Germans are very adamant about the protection of privacy.

The problem starts if you go around in public, making hateful speeches that incite violence.

That sounds like a great way to protect those who commit acts worthy of hate from any public remonstration.

You are absolutely and perfectly allowed to speak out in public against such people. But you must be prepared to take responsibility if your speech is worded to spur people into violent action and to incite hateful action.

The court of public opinion is notoriously fickle. Rousing hate in the masses is not a reliable tactic, and often backfires.
