I'm not saying all trans-people must play trans characters or vice versa, I'm saying that it would be nice to have a transperson play one of those roles, or at least have more transpeople directly involved in the work.
The show sensationalizes the fact that the character is trans. It might not be 100% exploitative, but it's definitely not the right message, especially with her character based on stereotypes of transwomen. Instead of getting something empowering, we get a show that's going "Ooh, look! She's got a big dirty secret! I wonder how she's going to pull herself out of this mess!"
Sadly, many transsexual actors are cornered off into the pornography realm, and all we get in terms of culture is a byproduct of the sex trade. I don't know of any trans actors with a resume quite as robust as Sevigny's, but then again I'm not surprised considering the amount of oppression we have to go through. Mainstream cinema/television is hardly interested in empowering minorities. Kate Bornstein is a successful theatre actress and author herself, however, and Lana Wachowski (formerly Larry Wachowski, who along with her brother Andy, created the Matrix Trilogy) is releasing her first film post-transition in November this year: the film adaptation of Cloud Atlas.
Granted, Cloud Atlas doesn't have much to do with transpeople, and Bornstein's plays aren't exactly filling theatres any more, but it's definitely a start to have transpeople out in the world and creating their own culture. It gives younger ones someone to look up to.
Imagine a young child catching a glimpse of this show on television, and asking their parents, "Daddy, why are they saying that lady was a man?" to which the father replies, "Because she lived as one for a very long time. And she was very uncomfortable doing that, so she decided she needed to tell people she was a lady." The child's eyes grow wide and a look of confusion contorts their face for a moment, and they say "Well, why is that such a big secret?" After staring into the television for a while, the father replies, "Because people are scared and confused. Just like all the characters in the show. And many of the people who watch the show. It's exciting because no one talks about people who change genders." The child, even more bewildered, says "I don't think that's something to be scared of. If I want to grow up to be a lady, then I should be able to tell people, and feel proud. This show is bats*** insane. F*** the patriarchy." Slowly, the child saunters back into their bedroom, and the father smiles to himself, as he gets up and smashes his television on the floor.
My initial reaction might change once the show comes out and I actually see an episode or two, but right now, I'm just annoyed with it.
