I'm well aware of what the definition is, however it only defined anti-social personality disorder, under which psycopath and sociopath fall, but it does not define sociopath, which is not recognized as a true mental illness, but a set of behaviors that differentiate between a psychopath and a sociopath. But if you do a bit more reading, you'll find that sociopaths have a different set of behaviors. I'm well aware that they believe that sociopaths, they believe, are started by a significant emotional event around age 15. But the symptoms are as I described. I'm sorry you dealt with severe mental illness in your family, but that doesn't necessarily make you an expert on sociopaths. I think if you do some additional reading, you will find that throwing the DSM around when talking about sociopaths is meaningless. So as far as I'm concerned you don't know your sociopaths from your pschopaths. But then, you do believe you are a master of the universe of every subject. Perhaps you should speak to your therapist and they can help you understand sociopaths, as well as your need to be an expert on every subject that comes up.
