I wonder why such a misinformed and misleading post is deemed insightful by forum members.
Firstly, in most European countries, the right to free speech is not actually legally or even constitutionally enshrined. There is the usual right to assembly, free thought and a freedom to adhere to any creed one wishes, but in most European countries Slander, Inciting to Hate or public unrest and Defamation are all illegal under criminal law, mind you. Therefore, as a default, there are legal limitations to how free speech actually is. And this is a good thing.
When the "free speech" mob starts trotting out "censorship" as a mule to flog, I get a little tired. In a world that contains 7 billion people of all colours, creeds, genders, races and beliefs, one should not strive for completely unmoderated speech. Because there are too many narrow minded morons in this world, it would descend into chaos and anger. As my grandfather wisely used to quip: You can think what you like, but you can't say whatever you think.
That out of the way, the legal definition of hate speech is quite well defined in a number of European countries as well, and prosecutions can actually be realised. Specifically the Germans have *ahem* learned a couple of painful lessons from their own history, although it must be said that Europe between 1860 and 1940 had large institutionalised racist agendas with the so-called "Race-biological Institutions" in various countries, so by no means do I want to single out the Germans as the only purveyors of a certain breed of thinking. So while this is not a reductio ad Hitlerium argument, one must be vigilant of the possible consequences of unchecked hate speech, "Volksverhetzung", "Aanzetten tot haat", "Agitation publique" or whatever you wish to call it.
As for those who actually use social media to spread poppycock, hate-speech, racism, bile, xenophobia and religious fervour alike, I for one do think it would be great if these people be prosecuted to the full extent of the law. The law is there to be enforced, whether you intend to kill, steal, embezzle, con or incite to hatred. But the lack of editorial decisions from Facebook's side is something they should indeed be held accountable for. Facebook serves as a news outlet to some 38% of the American public. I shudder to think about that, given the amount of moronic vitriol and cat video's that permeate that network. The likes of Google, Facebook and Twitter wield quite a bit of power, and their corporate nature drives them to shun any form of responsibility.
From my perspective, it is heartwarming to see a nation state such as Germany finally spring into action to protect the education, sovereignty, privacy and safety of its citizens by holding these media corporations (which they are by now) accountable for the information they provide to said citizenry.
