I am a cis man in a graduate program. I am currently enrolled in a Zoom discussion group led by another graduate student, “Susan,” who’s lovely and kind. I have noticed on two occasions the leader using incorrect pronouns for another participant, “Tom.” Tom has never verbally mentioned their pronouns, but they are listed next to their name on Zoom. Tom has not corrected Susan publicly, though I have no idea if they’ve spoken privately. I have never spoken to Tom outside of the discussion group. I can’t be sure, but I believe Susan would be embarrassed to realize her mistake. Would I be overstepping to send a note to Susan informing her of this error? I worry that I’d be speaking for Tom or sorta-outing them, though their pronouns are visible and clear on Zoom. What do you think?
