Who is arguing for a backdoor? Do you actually know what are the proposed technical approaches or are you making assumptions?

What is not possible?

> all these stupid "chat control" like proposals

For example here, you make your argument by stating that these proposal are "stupid". There is no effort that I can see to even try to understand where the other party is coming from.

And that is an issue, in my opinion. I think that a productive and honest conversation about a complex issue like this one requires empathy with the other party's position.
