The boss who fought tooth and nail to get HR to acknowledge my transness and change my name (and failed because HR was a bunch of cissexist jerks, but that's a story for a different day) was also extremely racist and would not have done nearly as much for me if she'd known I was mixed.
The teacher/coach who helped me work through some of my horrible depression was very openly one of those Catholics who despises queer people, and would not have helped if she'd known I was trans.
The psychiatrist who helped me get antipsychotics that allowed me to stabilize myself was disdainful of addicts; if she'd known I'd been one, she would not have prescribed anything to me.
You either die closeted or live long enough to see all of your heroes disown you, I guess.
