I was taking a small reading pause by going into the else-proclaimed father and guru of opensource software Richard Stallman, famous for including non-binary or sexist lingo in his speeches, and found this gem:

To quote:
He proposes a few good solutions that I haven't quite heard yet.The proponents of "they" argue that it is the correct choice because people have long used it occasionally in the singular. While it is true that people did so, that shows only that they faced a similar choice between bad options. Some chose "they" as the least bad, but that doesn't make it a good solution.
Have a good read and do tell, do you agree?
