Atheism

I think its more a push toward making space for people who have marginalized identites to act. For a long time being openly queer was career suicide. So now that those stories are finally being told, people also want actors writers and producers of those identities involved in the process.

I think its less that straight actors cant play queer characters and more so that there are already plenty of roles for them. Maybe in a more equal future that pressure wont be there but right now it is.

I also think it depends on the role. A side character that happens to be gay? Yeah a straight actor can definetly play that. A lead role in a comming of age tale about discovering your gender identity? Probably best played by someone who has lived experience.

Imo it's the same idea as having black people play black characters instead of white people with black makeup. If everyone was treated as equal then it wouldn't be an issue. However, that's not reality. People are treated differently based on gender, sex, race, age and so forth. Wanting queer characters to be played by queer actors is a way of making sure they have a space to demonstrate their skill, talent, and potentially make a living off it. Same thing with black people playing black characters, or women playing female characters.

There's another element, however, in which good acting can't fully replace personal experience. A queer actor playing a queer character will likely be able to identify with said character much better than a straight actor could, and as such, they would be able to harness their personal experiences and channel them through the character they're playing.

While my latter point doesn't refute your point about straight characters being played by queer actors, the former hopefully explains why it isn't universally applied. I do believe though, that in a just and equal world, things like sex, race, gender and so forth shouldn't be (dis)qualifiers for any given character, it's just that we don't live in that kind of world.

To be fair I never said "can only be played by" just that the gold standard has become preferred casting of actors who can apply their personal experiences to the role be it people who come from a specific place or culture (like a queer culture) , have a specific racial background or a disability those roles particularly are earmarked with a growing cultural preference for people because there's some wider cultural issues of stereotyping, typecasting or framing out people who can tell you is something the playwright put in is full of shit. More people are becoming wise to media literacy and can spot things off with an uninformed take on a performance.

There is a silver and bronze standard that are still acceptable. Sometimes you cast someone outside the gold standard for a bunch of reasons. Availability, overwhelming directorial notions that it was an audition above and beyond... but in leftist spaces particularly - like audio drama podcasts as an example the gold standard of preferred applicants is explicitly listed on audition sides.

I'm not sure that I agree that a queer character can only be played by a queer actor.

Maybe not, but having it played by a queer-hating religious zealot won't do.
