> For all I know, countless people refer to me with female pronouns in discussions I can't observe.
Do you think you might feel differently on the topic if they did it continuously in discussions you can observe and when you tried gentle correction you were met with overt hostility?
The situation you describe is entirely inconceivable. I have knowingly had transgender people in my life for about two decades. I have never seen a "gentle correction" "met with overt hostility". I have only ever seen acrimony in explicit debate spaces, when people chose to make object-level examples of themselves for emotional appeal. And people simply do not "continuously" refer to other parties to the discussion in third person, at all.
