I think it's really as simple as "If I can't have that thing, it hurts less to know that noone else can either." For queer players, being denied something that a straight player can have just feels like twisting the knife.
Which is why I always try to make sure I'm focusing on homosexual representation when I talk about representation.
I'm not particularly interested in having set sexualities for the benefit of heterosexual players. But when a few gay people tell me that they really appreciated it, it makes me pause and wonder if I should reevaluate. I'm significantly more interested in giving queer players something and denying heterosexual players a piece of content.
I think it'd be interesting if the most sought after characters were actually the gay characters.
I hope that makes sense and helps you understand a little better where I think at least your queer audience is coming from.
I can understand it. It's why I am a big supporter of choice being available, and can greatly understand the equivalence of choice. I mentioned it in my wall o' text, but it was interesting and eye opening to have someone tell me that, frankly, they enjoy the idea of having a gay romance be solely gay simply from the perspective of "it feels like content that was specifically made to acknowledge me and that felt great." I realized that it's something that I take for granted because content is often made "for me."
