Caitlyn Jenner did not win an olympic medal. Bruce did. In trans politics our old persona is dead. Hence the term dead name.
Caitlyn may be holding onto her dead self because she has no other self. Any other transwoman would say 'Who are you talking about?'. If they were berating Caitlyn because she's trans- That's a no no. If they were giving her a hard time for her politics, or public statements- Fair game. She's an idiot.
