Having been in a "psychiatrist section", I can vouch for the idea that you don't come out any less trans. Why exactly is he angry, does you existence offend him on a physical, religious or ethical level or is it just the money that was spent for your surgery? If you're truly stuck there, a good survival technique is to lay low, and use "I" statements to diffuse the tension. For example: "I think maybe we should talk about this another time" is going to land better than "You aren't listening!".
