I have to admit I don't know a lot about Taylor Mac and Mac's career although I did see Hir at Steppenwolf. Besides the pronoun "judy", does Mac really use "judyself" as the reflexive form of "judy"? Does Mac have a preference for an adjectival possessive form for "judy" or does judy simply use "judy's" instead?
Steppenwolf does a talkback after every performance. At the Hir talkback, I don't recall if those participating were instructed about Mac's pronoun choice.
