When many people keep misunderstanding what you say perhaps the problem is with your poor communication style, not their comprehension.

The latter article also describes a study suggesting "matched controls" (read: siblings of mentally ill people) are also disproportionately violent which is interesting.
Many citations are provided therein. I didn't provide it because it's completely tangential to the main point, namely that there exist crazed and violent people who should be tazed and tied up. I'll note you didn't provide a citation either.
(The SOMD link isn't loading for me) Note that all but one of your links involve drug abuse. Here the violence isn't due to mental illness, but to drug abuse. Drug & Alcohol addiction is a predictor of violent behaviour. (Much stronger than mental illness.)
