Would anyone in good faith, with only two options “Stereotypical Brodude or Fashion Magazine Cover Girl”, is going to play the former with she/her or the latter with he/him?
I think so. Why not? There are as many valid genders and identities as there are people in the world. Who am I to judge what people want to be referred as? Also even if there wasn’t people like that, I can almost guarantee there are people who would want to put a “they/them” to those body types, which seems to be the main point of this body type trend.
I don’t see it as a bad faith thing to be like “hey, we should include the ability for NB people to have their preferred pronouns”
Again, I agree that having more options would be better, but why does perfect have to be the enemy of good?
Edit: I also want to say that NB does not equal androgenous. Sure many NB people may desire or have an androgenous look. But I also know people who like to look and be feminine but are still NB, and the other way around
