So how is Volksverhetzung, which is defined by law, any different?

That’s a speech law, thus it would be a circular argument (I.e. your speech violated a speech law).

You are completely missing the point. Because those laws exist, the argument for "free speech" and against censorship is ignorant. We don't have free speech and never had and never will, no country on earth has, because it's ridiculous to the point of been childish. Speech is not free, it has limits, like everything else.

And about Alex Jones, the case proves beyond reasonable doubt that he should had been censored to prevent the damage and that is my point. His speech has real life serious consequences that hurt people even if he didn't do it personally and he didn't intended to happen.

No, you're looking at it in too black and white a way. It's not a decision between "no limits to speech at all" and "any limit is fine because free speech doesn't exist".

The line, at least in the US, is that all speech is free unless it "incites imminent criminal behavior". And no, the criminal behavior doesn't include criminal speech (that's just circular logic).

Yes, the line the US draws favors free speech far more than almost any other country. And that's a part of the ethos of our country. Other countries are free to do whatever they want.

And no, Alex Jones shouldn't have been censored (by the government). We don't allow the government to arbitrarily deny citizens rights unless they have been given a fair trial. In his case, a judge decided his speech fell into the realm of defamation and thus his victim was due restitution.

And that's how it should work. We don't need "speech police" and we don't need to create new laws to further remove people's rights. If someone oversteps the bounds of free speech then a judge can decide what to do, not Facebook.

The line in the US is that you are free from retaliation by the government.

Private business and private individuals are free to set whatever rules they like about your behavior in their establishments.

They're also allowed to just not listen or want to repeat it.

If someone shoves a bunch of pamphlets in my hands, I'm allowed to dump them in the trash.
