This is a thread about mental illness, and you are using slurs associated with mental illness ("crazed"). If you're not talking about mental illness you probably need to be more careful with your lazy use of stigmatising language.

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

Your inability to provide a cite has been noted.

A quick google search suggests various mental illnesses (bipolar disorder, schizophrenia, and the catch-all "serious mental illness" category) are strongly linked with violence.

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.
