Freedom of expression never means that other are not free to voice their dislike of certain opinions. And while some expression is frowned upon other members of the public you are still within your legal rights to express them. The line you can not cross is incitement of violence, denial of the holocaust, breaking NDAs and so on. Contrary to what many Americans think, Germany is not a oppressive country that censors you left and right, but actually has relatively similar free speach rights to the US or other western countries.
>> Germany [..] has relatively similar free speech rights to the US or other western countries.
At least since NetzDG was passed I'm not sure it's quite that simple.
Google[0] says this about the NetzDG:
"The Network Enforcement Law (NetzDG) requires social networks with more than 2 million registered users in Germany to exercise a local take down of “obviously illegal” content [..] To qualify for a removal under NetzDG, content needs to fall under one of the 22 criminal statutes in the German criminal code to which NetzDG refers."
Politico[1] said this
"Titanic, a German satirical magazine, was similarly barred after parodying anti-Muslim comments on its own Twitter account"
Can you give references?
In my experience of living in Germany, freedom of expression is welcomed as long as it's the right kind of expression.
