Second post of yours I've loved in 24 hours... marry me, if you're free.
I asked around last night, upon seeing the Playbill article about Olivo, and some friends told me that if a person's "pronouns" are "her/their" (and similar slash-hyphenate alternate set-ups), it means "I have no preference between these two." (Just what I'm told lately.)
"A" is for "affectation."
The ever-increasing alphabet soup game, dividing the entire spectrum of human sexuality into sub-sub-sub-sub categories identified by the first letter of the term-du-jour will ultimately render the practice meaningless – everyone's something. Distinctions between the million shades of sexuality didn't exist 100+ years ago (or 10 years ago). In 1902, Dorland's Medical Dictionary defined heterosexuality as an “abnormal or perverted appetite toward the opposite sex.” Twenty years later, Merriam-Webster gave the same definition. The identification of "heterosexual" vs. "homosexual" (new words, both) arose only in the late nineteenth century; and well into the 20th century, they didn't describe what you were, but what you did. Well, all that history could take books upon books, and have.
