Every teacher, instructor, professor I’ve had from kindergarten through graduate school across three states and as many decades has asked every class I’ve been in if a student has a preferred name over the name they’re officially registered with. Every one made a note in their register to call them as such. Refusing to call a student by their preferred name is a new level of pettiness at best and discrimination at worst. A teacher’s job is to make their classroom a place where children feel welcome and safe. Regardless of whatever their personal views are. So, I say with all sincerity and with no irony, fuck your feelings.
