This time it seems to center around the use of the English language (which does not have a gender neutral pronoun).
Is it possible to write gender-neutral (as opposed to say balanced) text and still entertain?
Yes. But if the audience is spending more time counting the number of times you used he and she rather than actually reading the book, then you haven’t a chance.
I write based on personal experience. There are no women in my gaming group and most of the guys do not choose to play female characters. When writing I do mix the pronouns but that’s more for readability rather than anything else. Referring to two male characters as “he” gets confusing, as would referring to two female characters as “she”. Which one do we mean? Bish, bosh, change one of them and the readability increases.
It still won’t be good enough for the people counting pronouns.
