If they feel society, and hence the media produced by it, isn't constantly reaffirming their automutilation and AGP fetishes, their low confidence in their delusion starts eating away at them. Thus, they assert that every fictional character ever made is actually was really a tranny all along, giving them the "validation" they so desperately seek.
