The point is that there's less of a repressive force from some areas and more of an attractive force to others.

There isn't a list of "These are the problem languages", it's an experience of "Oh, this community has a CoC that protects me and has a culture I'm OK with".

For example?

I am capable of making assumptions by myself, I fail to see how these assumptions are relevant in the real World, where I never observed them except for single cases that are everywhere and happen more or less with the same frequency.

I can't take an hypothetical as something that should convince me to use Rust because "some other community is worse in my fictional story"

The point isn't to convince you to use rust, it's to explain based on my experience why the phenomenon that's been observed occurred.

I can say from my personal life that I have avoided or actively gone to stores based on similar perceptions, and tend to analyze the same information whenever joining a new online community.
