I have enough experience with schizophrenia and mental illness to take a stab at this.
This is written by a schizophrenic, or someone in psychosis, or someone attempting to mimic that.
Schizophrenics are experiencing a very different reality than us, and psychiatry is inherently trying to tease them out of that reality-- which many of them reject. They are prone to paranoid delusions as well, so the combination of these things is very bad.
I once knew a schizophrenic person who told me about the "bad men in the white coats who gave him the pills that made the voice of Jesus go away."
He's figured out something that's partially true, many of the things we define as mental illness, are not. Our society causes some mental illness with the chronic and unnecessary stress is places on people. But he's incorrectly extrapolated that to "there is no such thing as mental illness."
