There’s no legal right to free speach in Germany and possibly other countries in Europe as well and for a good reason. That would also include the freedom to insult others and smear their names- just to give an example.

There is however the freedom of opinion and that is without any restrictions - apart from collision with other constitutional rights. You may think whatever you like - you may not speak out all of the bs in your head or be free from repercussions of the bs you say.
