Call a thing what it is

Do not blame evil on mental illness. It's a fun fantasy to believe that we can stop murderers from becoming murderers with Prozac and group hugs, but the fact of the matter is that the vast majority of mass murderers have NO diagnosable mental illness, and people with mental illness are far more likely to be victims of violence than perpetrators. 

Racism is not a mental illness. Evil is not a mental illness. Hate is not a mental illness. "The mentally ill" did not commit this crime, nor do we deserve to be marginalized and slandered in the press for it. 

This mental illness smokescreen is yet another ploy - lets us point our fingers at "those people," rather than examine the racism, hatred, and hypocrisy in our own hearts.
