I agree, if your dealing with a Narcissist please do your research and find out more about narcissism, borderline personality and their defence mechanism (projection, gaslighting, displacement, spitting, divide and conquer tactics, triangulation etc). Ignorance, fear and submission is what the narcissist feeds on.
AMEN! And of course their knowledge of narcissistic manipulative covert abuse makes them a threat! So he must destroy ur credibility with his smear campaign so he won't be exposed for the psychopath he is!
