A common trait of Narcissism is competitiveness. When a narcissist sees someone doing something that might get attention or the least bit of recognition, they are triggered to envy and competitiveness. And if the person who is doing this thing is deemed "lower" than the narc. in his/her head, the narc. will often do or say something to criticize or invalidate, or dismiss, abandon, or try to get other people to reject the person. Competition is the world they live in. If you have not been put on a pedestal by the Narc. as a "recognized Leader", then you are competition to them. They do not DO 'support' or 'recognition' or 'promotion', unless it directly serves them somehow.
