Turns out it still Really Bugs Me when people call Breq a female character. Yes, it would probably make misogynists mad if Ancillary Justice was made into a movie, but no, the main cast is not all women. They are all genderless.
Extra fun bonus: on re-reading, because Tumblr’s suggested post feature is really annoying, the post that prompted this actually didn’t say that the whole main cast is women. So they’re probably basing it not on (more understandable IMO) translation confusion because everyone is called “she”, but on the fact that that one character from a culture that does have gender, still calls Breq she, and people conclude things about Breq’s body from this. We don’t know anything about the plumbing of any of the other Radchaai characters. So. Yeah.
