but since that is entirely something I put on it and not something inherent in the text, then I must admit that there is no comment on sexuality.

It's not entirely something you put on it. It's the intention of the speaker as well as the cultural cintext. If someone calls you a b*tch, and you interpret it to mean dog, that doesn't make the comment not sexist.

Now, this next part I could be wrong about because I don't know what they actually put in the game, but don't you think it's sus that the writers specifically chose to include that line of dialogue for men exclusively and not any of the other identities you mentioned?

am saying it could imply a lot of things, and the fact that the OP assumes the game is calling him gay, speaks to a very defensive reaction, something that is typical for people who are insecure about their sexuality.

This is a pretty antiquated trope, honestly. Most homophobes aren't secretly gay or insecure. They just hate gay people.

As a bi person who is comfortable with his sexuality, my perception that this is a homophobic jab isn't based on any kind of insecurity, just social conditioning.

Referring to "everyone in the thread" seems disingenuous to me

I'm referring to other people in the thread because we're having a subjective disagreement about how to interpret language. There's no objective point that either of us can make on this topic. However, pointing to the room with many queer people who also interpret it as a gay joke is helpful to the conversation for this reason. It doesn't "win" the argument.

Yeah I think were just gonna have to disagree

Yes, I do believe this is what needs to happen, comrade
