This bullshit is not a "hate crime law", it is a law to silence opponents of the ruling junta. Worse, it enables blocking of US citizens (like me), that don't live in Germany, through dubious, semi-private entities, based in Germany. Both things are a scandal. And why does have Facebook problems in China? Why not grant the Chinese government the same rights as the German government?
How so? They are simply making people liable for breaking laws that already existed . How are they blocking you? How are they cementing their power by punishing people for inciting to violence against people with specific religious/political viewpoints or sexual orientations etc.?
Hatespeech. Criticise religion? Hatespeech. It would of course never hold up in court, but that doesn't matter, for social media platforms deleting anything that could be construed as hate by anyone who feels offended is the path of least resistance.
You are not made accountable for breaking laws that already existed, you are being censored for something that is not illegal, never was, still isn't, but could offend someone if it's disagreement on a sensitive topic. It's the end of any sort of free speech on social media in Germany.
