I feel like a lot of people here have forgotten what Titles are and are just lumping in gender in there now.
Titles are what people used to use to describe what they are (muse, philosopher, dilettante for example) and wasn't restricted to work.
So as one commenter here pointed out, goth, jock, etc would be titles, if used.
Gender was always meant to help identify where in the spectrum of sex one is. Whether that be male, female, both, neither, slightly female, etc.
Y'all are free to say your gender is goth, or as one user on Lemmy is becoming infamous for, Dragon; but you'll likely not be taken seriously, and ultimately you'll be setting back both progression for oppressed minorities as well as already existing accomplishments.
PS: op should say what neopronouns are for those who may not know.
