Human stupidity? As in allowing too much noise in the cities to the extend that people need to protect their minds?

The stupidity that makes depriving one of your senses seem like a sensible thing to do in a busy chaotic environment.

I don’t actually mind people doing that though. What is annoying is the entitled attitude that there should be no consequence for that choice, and everyone else should orbit/compensate around their lack of situational awareness.

Stockholm is a very quiet city, people still wear noise-cancelling headphones all the time.
