Projection is the great equalizer. Everyone the narcissist knows is equally guilty.
Their children, especially the one assigned the role of “scapegoat,” suffer the most from being projected upon. Trained to be humble and submissive, brainwashed to feel false guilt, they take on their elder’s vices without critical thinking. Bearing the “sins of the fathers” as a burden like Christian in Pilgrim’s Progress.
Spouses of narcissists suffer from a shit-load of projection too. They are in the unenviable position of being accused o’re and o’re of infidelity. Y’know, the infidelity the narcissists is actually engaging in.
Co-workers are also a dandy target for career projection. After all, fill-in-the-blank is never the narcissist’s fault, yet blame must be assigned.
