Honestly, "transfemininity enthusiast" doesn't make me think "chaser", it makes me think "transgender healthcare's equivalent to Dr. House, who has also gone full-on Bone Wars with third-gender burial sites, regularly writes 300-page linguistics theses on neopronouns, and has a full library at home of books written by trans women, lavishly decorated with commissioned paintings by transfeminine artists depicting key figures and moments in transfeminist history — not because thon is a trans woman, nor because thon sexually fetishizes trans women, but literally just because transfemininity is thon's decades-long (and surprisingly not creepy) hyperfixation".
And honestly, if that's what "transfemininity enthusiast" meant, valid.
