I mean it kinda makes sense? I'm like 90% certain it's not coming from the same mindset of the adamant "he or she" user, it's probably just an attempt to avoid the "those aren't my pronouns" embarrassment when referring to someone with pronouns that don't include they
not saying I'd do it, just saying I've seen enough interactions that, in my mind, would be enough to justify putting the two extra pronouns
they aren't going out of their way to use they, they just wanna be careful
