No we don't. The law is against insulting people, not against "saying stuff we don't like on the internet". The laws predate the internet by decades. The freedom to express your opinion is constitutionally protected, this does not cover all speech acts, in Germany and everywhere (see slander laws). Courts protect this constitutional guarantee, as several recent cases showed. Vigorously enforcing laws against insults and other speech acts that are hostile towards constructive discourse seems to me to be the only way forward when it comes to restoring a semblance of sanity to societal conversation. The social networks by themselves have proven to be utterly incapable of doing so.
The most comprehensive survey on various freedoms in the World that I know of ranks Germany at 94, ahead of France at 90 and the US at 86. (100 is the perfect score)

Freedom of speech is also a guaranteed right in the German constitution, as it is in the European Convention on Human Rights and the Charter of Fundamental Rights of the European Union.
In every jurisdiction there are limits to the freedom of speech. This applies to the US as well as everywhere else:
