Amen! As I believe we said on that other old thread (from before the forum had a like button). Oh, and this one too.
I’m always glad when people (especially my fellow privileged folk) say that they enjoy reading stories from a protagonist perspective not “their own.” Fostering that kind of discomfiting dislocation is one of the virtues of literature; it can foster greater empathy, open-mindedness, etc.
That said: there are plenty of people for whom social discomfort and dislocation (around, say, race, class, and gender) are an everyday life experience. I don’t think they’re under any obligation, moral or aesthetic, to seek out more of that experience in their entertainment reading. Privileged people who feel good about themselves for reading/RPing stuff that stretches their comfort zones ought to be careful not to get judgmental with people who don’t live in a “comfort zone” in the first place.
And as I’ve said before, I think it’s a mitzvah for authors of interactive fiction to give readers the choice to flip pronouns and orientation without changing anything else. In a world where most protagonists in popular entertainment remain straight males, and where the growing number of female and non-straight options are too often shoehorned into stereotype (sexy, sassy, etc), it’s a breath of fresh air to have stories where the characters aren’t determined by their sex or orientation – where we can have the same adventures regardless.
