This is disgusting. Here we see a list of reasons to discriminate against someone with a mental health issue, under the guise of protecting oneself from a condition which does not exist.
No significant psychiatric or psychological body acknowledges or defines psychopathy. They do not believe it exists. It hasn't been in the DSM since 1980, when it was replaced by antisocial personality disorder.
I would advise that future articles which present themselves as being about mental health be based on medical knowledge and part reviewed journals, not the magazines you can buy at a convenience store or something from the Huffington Post.
