Oh, sure.
It was just that from the OP, people are claiming “there are loads of actual transgender actors,” which for the claim to make sense must imply actors who aren’t keeping their TG-ness a secret. I can’t think of many – or indeed any – who are both TG and would carry the same “star quality” draw as Leto.
The whole point of an actor is to, well, act; they can and do play roles very different to themselves, all the time. Actors play Englishmen, fighter pilots, dwarfs, Klingons, surgeons, psychopaths, army Sergeants, amputees, hackers, dementia patients, without actually being any of these things because that’s their gorramn job. Are we suggesting we should’ve got an actual serial killer to play Dexter?
Let’s say for argument’s sake that there are loads of TG actors. So what? Are any of them the right actor for the role? This is basically arguing for positive discrimination; Casting could have the pick of the entire gamut of actors across the continents, why should they be forced to restrict their search to a minority subset?
I think I’m updating my previous stance from “non-story” to “whiny gobshites on the Internet.”
