Honestly, it makes a lot more sense if you view it from the perspective of Ashe.
She's basically anxiety embodied into a nervous wreck of a human being, even slight persecution of what she is might be more than she would ever be willing to bear, on top of the fact that it's a secret she's been guarding from a very young age, even if it would have been a minor secret, due to the length of which she's been hiding it from people will inevitably have a large emotional impact on her.
We haven't really gotten much information outside of duplos being persecuted because they're viewed as basically sexual beasts with no control, that could manifest in some pretty severe persecution or it might not have, we simply don't know as the dev hasn't shown us or told us yet. That being said, the dev did say that they weren't that interested in making some sort of social commentary so we might not get much info on how severe it might be.
Regardless though, it's important enough for Ashe herself due to how she is as a person.
