I'd like to see some of your material before I can judge. But the important thing isn't the manifest content of the fantasy, but what you do with it. You have to impose it on others in a way that they can experience it as an act of aggression. Any true borderline patient can employ projective identification, but a troll is able to project onto dozens if not hundreds without even looking them directly in the eye. For example in this thread, Vistaril Jr. forced others into a world in which you could almost fail out of medical school and still be actively recruited by Emory/UNC. You now have to live with him in his reaction formation towards psychiatry, a place that is both welcoming and humiliating. Then, and this is important as well, once the viewer is engaged in the enactment, dismiss them with something along the lines of "why do you care about me so much?" further frustrating their libidinal energy.
One exercise is constructing a medical student in your mind, one so thoughtful and intelligent you would love to have them as a colleague, but impressionable enough that they believe the words of a self-professed dance therapist who posts about dancing away from their client after a fall.
But that is all initiate level work. A true master is able to voice just enough misogyny/racism/homophobia that their audience inwardly cringes, but not enough to fully violate TOS. To help develop this skill, I would watch Fox News at least 16-20 hours/day. The clinical term for it is "Diet Racism":
