Would somebody in that community PLEASE buy a vowel!
“Oy” are two vowels that come to mind.
They’re the vowels in the English for holy ... which this letter perversion madness is decidedly not.
I think the next vowel will be “U” for “Undecided”. That way they can have a whole new classification that is so vague it makes them special and diverse. It also gives libs a way out so they aren’t committed to a particular group. Think about it. It fits right with them not allowing gender defining pronouns.
