Well there’s deadnaming on purpose or not trying at all, then there’s accidental deadnaming. Still can hurt. But please try to be understanding of us old farts with non-plastic brains who screw it up repeatedly. Some of us are really trying even though I’m sure it might not seem that way; we really can be that bad at reflexively putting the wrong name or gender in speech. Of course when corrected, we should immediately apologize and correct. I hope you can forgive us.
