i think this is actually an important social issue tied in with the infantilization and tokenization of autistics. we should really consider why there is such a massive overlap between transage and autistic communities, whereas neurotypicals tend towards headspaces and regression, compartmentalization rather than integration.
in particular, childish autistics are cast as age-regressors or fetishists (as playing-pretend or innately sexual), while sexually-active autistics are cast as too childish for such sex. it's a double-bind. but when those who view that childishness as a performance cordon it off, the regressors and headspacers -- the neurotypicals -- it tokenizes and fetishizes those qualities in others, those who are not frightened to be childish in their daily lives, or who simply have no choice in how they are seen because they are autistic.
youth liberation, sexual liberation, and autistic liberation are all deeply tied together through our social images of what a sexually-healthy young person should act like. that youth and neurodivergence are functionally sexual categories should tell you a lot about how taxonomy functions under patriarchy.
