Your pedantry is disregarded: "Pronouns" in this case has a clear and obvious definition that is not, alas, the original English definition of the word. Much like how awful no longer means "full of awe" except in the most pedantic of contexts, "pronouns" when used in the context of "listing my pronouns" or similar phrases has a clear and generally linguistically accepted meaning that is not "the replacement/placeholder word for another noun used earlier", but rather "gender identifier words you must use in private away from me to address my own vainglorious image".

I know, I know. But I can't resist the urge to be pedantic.
