I agree with everything you said, but I don’t think it’s fair to blame “mentally ill” people. Not attacking you or anything but I think it was a poor choice of words in this case, and way too broad a brush to even apply :)
I’m not totally sure what you mean there? I’m not saying that all mentally ill people are prone to that, I’m just saying the inverse: that most people who are prone to that are mentally ill. It’s certainly a very very small subset of mentally ill people, if that’s what you mean.
