Well, it's quite clear that for the purposes of the actor debate, TRAs are being very specific in their definition - they mean someone MtF or FtM. This is very much what I meant about wanting two contradictory things. Essentially, there is a desire for representation, but and equal desire for everyone to pretend that certsin people pass. This won't really work with non binary stuff, because almost every individual is, and it would make very, very flat entertainment to have each character a simple binary stereotype.
What is meant I should imagine is stuff like the Emmerdale situation I mentioned earlier, where an individual actor is born a certain sex and now presents as the other. It's very visible and obvious. Because essentially there's not a lot of point in pressing for visibility if no one can tell.
I can understand that, but it's got a limited shelf life as an approach, as LGB people are finding out - at first it was about presenting some gay characters, all good. Then it was a case of giving them positive storylines, again, a step forward. Then it was a further step to show the real lives of LGB people, rather than incessant tragedies or coming out stories.
But now the challenge for LGB representation onscreen is how to just have a gay character without needing to do more than a few signals the way you would do with a heterosexual character - the sight of a partner, specific casual dialogue and so on.
The Trans lobby will find that bit more difficult because a certain sector are so very, very invested in attention, and especially the part that pretends to want to break the gender binary but completely conforms to it, a la Fox and Owl looking like any old bog standard heterosexual couple so they have to keep holding up signs to set themselves apart.
