Replacing “transsexual” with “transgender” may be more modern and would hopefully stimulate a bit of discussion. As a retired member of that foot-dragging community of whom you speak, perhaps a small historical note is in order. The term to which you object was used quite commonly until around ten years ago, even among reproductive endocrinologist who had a lot of trans patients. But our language evolves, so it will be interesting to see if anyone else picks up the discussion.
