Little linguistics exploration here:
The usage of "they" is not misgendering. It cannot be as singular "they" is a generic pronoun referring to both male and female people.
Singular "they" has been in use since the 14th century. And actually predates the use of "he" as the ostensibly gender-neutral, generic standard to refer to male and female people (despite that accepted meaning, we know from contemporary writings "he" was consciously promoted to portray men as the default, the primary sex).
In the 18th century grammarians started proscribing singular "they" and demanding the use of "he", this intensified over the next 150 years. By the middle of the 19th century there was even act act in the UK parliament about the use of generic "he".
What would be quite fun, I think, just to drive home the absurdity of not being allowed to name males as male on a feminist board (where we all know how important it is to name males as male because that is the sex that oppresses us all), so what would be equally absurd as that rule, would be to use the wrong verb forms with singular "they".
By convention, it isn't used with third person singular -s verb forms. But maybe we should.
Example:
McK is cleary as ignorant about grammar and etymology as they is when about sports science. Could have some fun with this, what do you think?
