You said "keep your politics out of the games". So, again: what is political about Dorian and his personal mission that is not-political about depictions of heterosexuality and heterosexual characters? What is political about not having anti-gay dialog options ... yet not calling for anti-straight options at the same time? Why is the constant, in-my-face, political heterosexual agenda not in fact a political agenda? (Irony alert again, just in case.)
Likewise, why is "political" for characters to refer to a trans man by the proper pronoun -- but not-political to refer to a cis man by the same proper pronoun?
Treating gender identity and sexual orientation as "political" only in some cases and not others is deeply "political" in and of itself.
There's nothing intentionally political about Dorian just *being* gay or of any other particular character *being* whatever they are. Up until this point, nobody's orientation (straight or gay) has been held up to a spotlight with an explicit message of "consider the issues that X's orientation causes for them." Orientation only becomes intentionally political when someone points to it and says "you should pay attention to this because *reasons*"
You can make an argument that the *exclusion* of the very existence of gay people is a political statement, but it's not really one that applies to Dragon Age, where gay/bisexual people have obviously existed since DAO. And even so, it's usually not an intentional one. I mean, which would be more a political statement? A game that just happens to have no gay character's because of oblivious heteronormativity. Or a game where developers explicitly said "we aren't putting gay characters in our games because we don't support gay rights." Or on the other side, which is more political: "We are including gay characters because many of our customers are gay and we want to make content for them too." or "We are including gay characters because we want to make a progressive statement about the issues facing gay people today."
I've never once been advocating that gay people *shouldn't* be in the game. I'm saying that since they are in the game (because gay players like everyone else enjoy content that keeps them in mind), I'd prefer it wasn't used to make overt, intentional political statements. Just like I don't want Vivienne to start talking about police violence. Just like I don't want Cassandra to start talking about discrimination against women in the workplace. Etc.
