So much of the queer community Hates fluidity. Identifying as genderfluid or abrosexual is fine until you actually specify what genders or sexualities you're fluid between then it's "you're not a REAL lesbian" "you're not a REAL girl" etc.
Unironically it's "you can say you're fluid but saying how you're fluid immediately invalidates it" which is backwards ass binary bullshit.
