I recently watched a series called "Sense8" on netflix. One of the characters was a trans woman and was played by a trans woman. The American TV show "9-1-1 Lone Star" has a character that is a trans man that is played by a trans man. It's happening, just not as quickly as some would prefer.
But I do understand the conundrum. If the story is about the "in transition" person, perhaps having a woman play the role makes sense if that's what they are focusing on. I do think, however, that having a trans male play that part lends some authenticity to it. Overall, it's an evolution. More and more they are getting Native American people to play Native American roles (notable exception recently was Johnny Depp as Tonto) and having black actors play black roles, etc. In the 60's Natalie Wood (Russian/Ukranian decent) played a Puerto Rican in West Side Story. In 2020, they'd choose an actual Latina actress.
I don't necessarily get outraged over the "white washing" (or cis washing as it were here) like many people do. I do often shake my head wondering why they chose a particular actor to play a clearly different ethnicity for a role. Doesn't stop me from enjoying the movie/show if it's entertaining, though.
