That is not true at all. Actually most mentally I'll people are not violent. You really ate wrong to trust to define criminal behaviour as a mental illness.
I've never said that most mentally ill people are violent. Why are you making things up? Do you really think assaulting people at random is sane?
I'm arguing that violent criminals have mental issues. You are turning it around and trying to make it seem like I claim all people with mental issues are criminals. This is not cool.
Violence is very natural. Hardly a mental deficiency. You keep saying all criminals have .dental deficiencies, which is objectively wrong. Your definition isn't the definition.
