As for the post on narcissists not being insecure and actually being psychopaths, this is not at all true, by the version of narcissism I use it by the dsm version. Of course there are narcissists who do terrible things... But this notion of narcissism is completely false.
The DSM version states that the cause of narcissium is still unknown. Could genetic, could be enviromental, could be both.

The narcissists Ive known have NOT been insecure, this 'insecure, false self' stuff is actually totally unproven, its simply a guess from Freud 100 years ago.

People are very loath to change old ideas.
IMO experiance its mostly genetic, couple that with a dysfuntional upbringing and you have a full blown narc.

Narcissists are not the same as psychopaths, but all psychpaths are narcissists.
