There was a multi episode story arc about a teenager (forgot her name, had a teenage boyfriend and got adopted by Stamets/Cullen) coming out as non binary and choosing they as their pronoun.

It was very heavy handed on drama, whereas if there was any internal consistency, there wouldn't be any "coming out" at all because "staying in the closet" wouldn't be a thing. The whole thing felt like having a Jane Austen dialogue in present Norway.

I would love to be able to say this was a one off occurrence, but pretty much all dialogue is heavy handed, with excessive drama not supported by the fiction. While TNG is rather under acted, DSC is heavily over acted. Out goes technobabble, in comes soap opera.
