Chat Control Must Be Stopped – Now

I find it somewhat disturbing that this sort of thing is not considered a career killer for politicians.

Almost nothing is. Local politicians fail upwards to the EU (at least in Germany) or some private job, if they fail at all. Most of the time, you can do what you want, and the voters don’t care.

"and the voters don’t care."

Then why did so many vote extremist anti EU? There just has been EU election in germany and the nationalist gained a lot. And none of the big parties otherwise said a clear no to that, so what could I do, except vote a small party against that, but too small to really do something?

Voters care. But they see often no point in voting anymore.

How many people did actually bother to vote in Germany?

Here in France, the "extremists" got a bit over 30% of votes. But turnout was only 51%.

According to [0] average turnout is 51%. Some countries have very high numbers (IIRC voting is mandatory in Belgium?), others ridiculously low. This, to me, means pretty much that "voters don't care".
