There's an Irish commenter, Aidan Comerford, on the whole trans issue who I know nothing about other than he keeps popping up on twitter.
I have absolutely no idea who he is, but he appears to be even more invested in the process, from the opposite persepctive, than Linehan. A cursory glance suggests he spends approximately all day every day chasing Linehan, Rowling etc looking for evidence of transphobia.
