What I find interesting is that they've only included categories for best male identifying role and best female identifying role and the same categories in supporting.
Surely if you wanted to be really progressive you would have non-binary and the other infinite number of genders. So someone in a non-binary role either couldn't be nominated or they would have to claim that role as male/female identifying.
Makes much more sense to do it based on the sex of the performer rather than the gender of the role they're playing
