do you think it would have been preferable for 'non-binary' to be called something from an in game language? like maybe taash could have used a rivaini word, or an elf/dwarf rook could have used a name from their own language? i personally don't hate non-binary being used but feel like in addition, expanding upon in game languages would have been cool too.
I personally see no problem with it either. Especially because if you don't spell it out that plainly, there's gonna be people arguing about how it's "not really enby" or whatever.
Fictional worlds can have all sorts of things not directly derived from either what is expected to be their inspiration or within themselves, but specifically the moment it has anything to do with suppressed groups, people began to get pissed.
Thedas has nonbinarity, has it by that name, and if someone doesn't welcome that, they should deal with it.
Of course, it is good if it also has different manifestations and names for similar concepts, just like in real modern world as well; and just like in real modern world, they can use "nonbinary" in more than one place.
And very yes to the "if it was a different term people would be arguing that it isn't really enby"
