I think you have a very good point there, Mighty Mouse. Mental illness doesn't cause shootings. The isolation and anger over mistreatment would be significant factors. I think that there does need to be a focus on mental health, because people with mental illness deserve to receive appropriate treatment, and because if people understood mental health better, stigma could be reduced and people could do a better job of being aware when there is someone isolated, emotionally wounded, etc. and could reach out to them and help them to feel like they are a part of the community. I would never go on a shooting rampage, but I relate to how hurt and excluded people must have felt before they got to that point, and I'm sickened that it seems to be happening to so many people.
