You're misunderstanding things. It's pretty simple. Given SS main public, people are okay with incest, having sex and impregnating women and female creatures in general. It's the audience fetish and the main reason DC earns almost $60k per month. Gay sex, on the other hand, isn't the audience fetish because the game is about a straight male protagonist (the exception so far has been trap Eve however even there MC's ass is intact). I'd never go too far wishing DC's death or cursing him, neither I'm against homosexuality. However, if there's something being developed that isn't my fetish (for me, gay sex, guro or scat), I wouldn't support the project. Simple like this.
