Therapy is about leaving people more “how they are” than before. It’s not about making them behave according to expectations.
I know very well what therapy is about. Decades of experience. Being an autistic person and working through a life of internalized ableism and discrimination works wonders for recognizing it. Not being able to understand sarcasm or other subtext is no problem for me, it is a problem for my surroundings so they can go to therapy for it. I go to therapy to learn to not accept being ousted for being different.
