Again, I'm not denying verifiable reality, you are not reading correctly.

The article mentions the sentence in the following paragraphs

Indeed, from the campaign trail in the east Berlin district of Lichtenberg, von Storch told Drop Site that “‘From the river to the sea’ means kill all Jews—I don’t think we should have that free speech, I don’t think that’s a good idea.”

Dayan had provocatively uttered the phrase, “From the river to the sea, Palestine will be free” on social media in response to an article in November 2023 saying that the slogan should be prosecuted.

-> not illegal, just some idiots calling for it to be illegal

Here, just for you, from me who lives in Germany, where it's not illegal to say it: "From the river to the sea, Palestine will be free."

And I mean it, because what Israel is doing is simply a genocide. But that doesn't mean you can just change reality to what you think it is.

And honestly, if you read and understood the article, it shouldn't take much time to search for the terms you know and then copy that into a comment to prove me wrong.

... Because that is exactly what I did with this comment, proving you wrong that the sentence you wrote is in fact not illegal.

Edit: after checking Wikipedia, I have to partially retract my statement about the legality. The ministry of inner affairs ordered Hamas as terrorist organization and the saying as its slogan and forbid it. However, multiple courts have already overturned that decision and stated that the saying is not illegal in itself, only if its meant as direct support for Hamas. So I was wrong, but the Wikipedia article explained it much better than the posted article.
