To be fair, it kinda feels like it's being marketed that way.
"It's a very binary portrayal of gender (which makes sense for a period piece –– it's set in 2015), so cue the discourse in 3...2... "
I guess I'll take that bait!
I was thinking about this too, and I even considered bringing it up in my first post, but like you I was a little wary of opening that can of worms. After some reflection, my feeling is: yes, it's very binary, and I can definitely imagine some trans or non-binary people seeing this play and feeling left out of its discussion of gender, and that's a totally valid reaction.
However, it also seems to me that Nogueira is knowingly choosing to focus her examination on the specific dynamics that exist between cis straight women, cis gay men, as well as "straight-passing" men. Despite being rooted in a false binary, the intricate dynamics between these groups DO exist, and are worth examining on their own terms. It's the difference between saying "let's talk about gender, and here are the two genders!" vs. saying "let's talk about cis straight women and cis gay men, because there's something interesting to explore in that relationship."
It seems to me that a playwright in Nogueira's position is well within her rights to say "I can easily fill a 2-hour play with everything I have to say about this specific subject matter; and if I broaden it, the play could be 4 hours long, AND feel less focused, and I STILL might not do it justice because I'm not a part of that group." So it seems to reasonable to keep it focused and specific so that she can actually say what she's trying to say about the subjects she's choosing to tackle.
It feels like the long-term solution is simply to say: plays like this can continue to be written if it's done with a focused intent, and not with a broad stroke of generalizations that actively seek to uphold the gender binary. But meanwhile, we really need more companies to produce and uplift plays from trans and non-binary artists that add their own voices to the broader conversation.
But I'll add the disclaimer that I'm a cis straight man, so maybe there are some problematic nuances to the play's representation of gender and sexuality that I missed, and if so I'm happy to be challenged on anything I said above.
