Ilia, as far as we know, is homosexual. This was shown during a confession that she either had, or still has, feelings for Blake. There was another scene where Female Rabbit Faunus (credited name) traded blushes with her.

So how is her homosexuality well written? There are a couple of factors that you’ll need to take into consideration.

The first is that Blake doesn’t react negatively to the fact that Ilia had feelings for her. Blake’s not in a great mood, but it’s not because of her homosexuality, it’s because she’s feeling either betrayed or disappointed in Ilia at the moment. In a later scene she has to pin Ilia to the floor in an attempt to convince her to change her ways, that conforming to Adam’s way of thinking (that one race is better than the other) is wrong. The scenes aren’t centered around Ilia’s prior or current feelings for Blake.

Her homosexuality has been written in passing, focusing more on her personal character than a single trait. Because, as somebody who’s bisexual, I think that focusing on the sexuality in a piece of writing that’s set in a world other than our own is honestly pointless.

Even in series centering around a homosexual relationship, write the relationship itself as a relationship before you treat it like a homosexual one. Most homosexual or bisexual people don’t just change how they approach romance because the other party is the same gender as them (or transgender).

If you have a differing opinion, I’d like to here it. Just make sure to give me reasons for your opinion rather than just tell me that I don’t know what I’m talking about.
