Karl Popper, "The open society and its enemies":
https://en.wikipedia.org/wiki/Paradox_of_tolerance
It's all about the paradox of tolerance.
That chat control attempt is a direct result of the paradox of tolerance.
The thing that makes me sick to my stomach is that some of the worst of worst intolerant discourse is going to be allowed and protected because it's "religious": because we are open, tolerant, societies we are tolerant with intolerance.
If you have a holy book that calls for killing non-believers and taking their wive and daughters as sex slaves: that's fine because, see, it's religious.
If you want to discuss that holy book online with your fellow believers: that's fine because, see, it's religious.
But any talk criticizing that is going to be criminalized, crushed, pointed out as "far right" or any non-sense like that.
It's shooting the messenger.
Guess what's one of the issue concerning many people in a great many european cities at the moment? People feeling that religious extremism and obscurantism, middle-age style, is making a comeback.
And people are organizing marches all over the EU.
The last thing the EU wants is people on social media organizing themselves and protesting because they don't want the EU to become the next Syria or Somalia: most in the EU do not want the EU to become an intolerant continent.
You could say that any chat control is bad. But that chat control is going to be used prevent the criticism of intolerance.
It's really sad: I already moved three times, lived over four different countries (all in the EU) and now I'm planning to leave the EU while I still can (not that there are that many great places where I can realistically go).
P.S: for those in the US you should cherish your first amendment
