JBroadway said: "@joevitus, the "lack of consistency" that you're noting comes from an impulse to balance what's already unbalanced, and account for the nuanced realities of the past and present.
In a world without systemic oppression, anyone could play any role, but we don't live in that world.
On a practical level, it partly has to do with job availability. When someone faces systemic obstacles that make it more difficult for them to get jobs, active choices have to be made to counter those systemic obstacles. There are very few roles written for trans actors, so when there ARE trans characters, casting cis actors denies them that role. And likewise, casting trans actors in traditionally cis roles is another method of alleviating the lack of opportunities for trans actors.
And on more symbolic / artistic level, we've seen historically that allowing marginalized communities to tell their own stories yield more respectful, accurate portrayal - and most of the time, it actually yields better art. Not always, not exclusively. There are of course, exceptions. But this is what the general trend indicates, and that, combined with the job issue, is really the heart of this "unequal" "inconsistent" viewpoint.
And ok, yes - maybe I was being a bit hyperbolic by implying that making Mary Poppins an actual trans character wouldn't change the story at all. But my points are that:
(a) addinga layer to the character doesn't have to change what the story is ABOUT at its core - Mary Poppins can still be a story about family, with a trans character in it.
(b) Yes, if Mary Poppins were trans, some people would find it distracting. And yes, we want to have stories that are specifically about trans experiences. But we also want to live in a world where a trans person can play a trans role without that being the entire focus of the character, and we only get to that point by creating more examples of it.
(c) frankly, IDGAF that PL Travers didn't envision the character as trans. It's an adaptation, and making bold choices like that can make the story better. I don't know if that's actually true of Mary Poppins, but I would be open to seeing it. I'm reminded of Maybe Burke on the Lortel podcast talking about how they always envisioned Cinderella as a trans character, because there's a lot in Cinderella's story that mirrors trans experiences. Maybe not true of Mary Poppins, but it's the mindset I'm talking about.
(d) After all that, a reminder again that we can have suspension of disbelief in these cases, and casting a trans actor in the role doesn't have to mean that the character is trans. Though with his clarification, it sounds like Mackintosh acknowledges this, which I agree is good (assuming he's sincere)
EDIT: I realize that some of these points above conflict with each other. Maybe they can't all be applied to the same work of art at the same time, but we can and should see all of these mindsets reflected in different stories, and any one of them could be a way of approaching a trans person playing a traditionally cis role."
Sorry for the delayed response.
I recognize that you want to create a more level playing field, and I want to see this, too, but I think there are a number of shows where this just doesn't work. It's too easy when watching the revival of Carousel with Joshua Henry to connect the race of the actor with racist stereotypes about how Black men supposedly abuse white women (or abuse Black women, for that matter; see the original novel of The Color Purple for what I'd say is a slur on Black men), which of course wasn't remotely in R&H's mind when writing that show. And I think if you cast a trans person who is obviously trans as, say, Mary Poppins (or Eliza Doolittle, or any number of roles), you have all sorts of problems. For one thing because a person's opportunity to live a trans identity in 19th century London was not what we'd call sizable. These situations just create a dissonance for many (I'd argue most) audience members that hurt the show. On the other hand, I don't think anyone would be bothered by a multi-racial Kiss Me, Kate, or having Tommy and Jeff in a revival of Brigadoon be men of color.
Yes, there are fewer roles for trans people and racial minorities on Broadway, and yes, this will continue to be true even as we open up more parts for them to play. And, yes, that sucks. But I don't think we can just cavalierly make nearly all white or cis roles available for all people of color or trans people for the reasons I list above: sometimes it just doesn't work. But we're only talking about specific shows that are part of the Broadway past, mostly the ones that were trying to create a realistic portrait of people at a time and place that didn't offer the advantages to either group that contemporary society does.
On the other hand, I think, going forward, more roles will be written in ways that will incorporate diverse casting depending on production, and also because, whatever the intent, there are more roles in contemporary shows that could be refashioned for people of color or trans people on the simple basis that more people of color and trans people are integrated into mainstream contemporary life. There's nothing about Dear Even Hanson that would stop any of the characters from being of any racial background because there's nothing going on there that couldn't happen as much to a person of color or a trans person. Nor is there anything like as strong a barrier to a particular social or economic life based on racial/gender identity, as there once was. This could apply to casting trans people in these roles, too.
