I bet I could de-stealth anybody in 30 minutes just by paying one of the thousands of agencies on the internet $20 dollars. There is ALWAYS a paper trail. Even people in withness protection can be traced (and some have been and killed).
Stealth doesn't exist, especially for public figures.
Journalist will dig till it bleeds into your past.
All TS who find their way in show business are not stealth and are doing bit parts.
Also remember that until recently the number of people who
transitioned was very low.
Another thing. succeeding in Holliwood is a combination of talent, looks and plain luck. The chance of anyone, let alone a TS, getting all that is very very small.
Although there is a lot of gays in holiwood, I'd be surprised
there would be more than 15%, a far cry from 50%. Also,
most are not actors, but are in the writing, producing,
costuming, etc. There's a lot of pressure on an actor who's
openly gay in hollywood even now, and many prefer
not being in front of the camera.
Since most post-op TS value their privacy, I don't why they'd
even want to go into show business where your life is exposed
publicly.
