With all due respect, this post might better be served on the "NPD:  Survivors" forum.  This board is for really for people who are NPD and may be looking for techniques to manage their NPD issues.

With regard to your title question, "What happens if you call a narcistic out on their crap?"  The answer is quite simple:  a malignant NPD will be placed on the defensive and be given the perfect excuse to launch a full-on smear campaign against whomever pointed out Truth.  And, there is no level too low for them to stoop to in an effort to achieve their goal:  ruin you, at all costs.  Pointing out the NPD's manipulations, lies, deceptions, etc., doesn't do one iota of good for anyone involved, including the NON-NPD-slash-source-target.  Yeah, we might feel better for having vented, as we should, but delivering our rants and vents to the NPD doesn't change things and only provides "evidence" for them to pass around to demonstrate how unstable we are. 

Randomness, I've been reading your posts and it's my very humble opinion that you may find serious benefit by engaging in strong counseling with someone who can help you to sort out your rage, anger, disappointments, etc., and teach you how to walk away and go "No Contact" without any regrets.  By going "No Contact," we are taking away any control that the NPD (and, possible sociopath) may wield against us, be it guilt, shame, defense, or offense. We can learn how to move through our lives without giving the NPD a thought, even if they are our own offspring or family members.  I say this from personal experience.

To find a good, strong counseling therapist, call your local "mental health" referral service and ask for the names of counselors (plural) who are familiar with NPD survival, sociopathy, PSTD, and abuse.  Then, engage with fearless hope in some powerful therapy.  It will take time, patience, and courage, but I promise, Randomness, that you will recognize and embrace the fact that only you have the power to put the NPD issues to rest and to facilitate your own healing from your exeriences.  I say this with utmost empathy because I have a son who was diagnosed a sociopath, and it has been a very, very bitter pill to swallow.  I still have moments of insanity when I want to reach out and attempt to heal and teach my son, but I quickly remember that there is no cure, treatment, supplement, or miracle that will address his diagnosis.  He is what he is, and nothing can change that.
