But now all the stuff about inclusivity in protagonists seems off topic… that was a writing-focused conversation, and was in the writing subforum. It really feels like there’s two separate conversations going on in this thread.
You might find this thread interesting!
That sounds concerning, but I’m not quite following what you’re referring to 
could you clarify the sort of behavior you’re referencing?
Catalina de Erauso—also known as Alonzo—is an interesting figure. From the early 17th century Spain, which was decidedly not a beacon for tolerance in pretty much any way. Um, and it’s a little tricky to determine what pronoun to use, since this is someone who lived as a man, but whether that’s due to being transgender in the contemporary sense or just due to wanting the freedoms is impossible to say. Anyway, Catalina was living completely as a man, doing a lot of fighting and dueling—not really a good role model, to be honest—and after being found out, eventually wrote to the Pope and was granted a special dispensation to wear men’s clothes! (Which, kind of ridiculous that one would need the Pope’s permission, but pretty interesting that he actually granted it!)
Also features in Rejected Princesses, for that matter.
Anyway, if this person could exist, a similar fictional character should be able to too.
And his horse is green too?
