Well, obviously it's up to you. My own preference is to do one of
determine the gender of the person you're referring to
use a gender-neutral pronoun
restructure the sentence so as not to need a gendered pronoun
use a construction like "he or she"
in preference to possibly misgendering someone, since I know some people find that very unpleasant. But if those are all too much trouble, fair enough.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
