Please don’t tell me to stop and breathe, I’m fully calm in this discussion.
My argument is that no one in this thread is a psychologist who has evaluated the schizophrenic person. Not you, not me, not anyone else. We can speculate as to the cause, but making prescriptive statements like “he did this because he has schizophrenia” only serve to stigmatize the condition further when we truly have no idea if that was the cause.
