The ratios aren't the point. It's down to how homosexuality is implemented, from what I remember the last time Rimworld came up in regards to gay representation. It becomes a negative feedback loop for the colonists who have the trait. People say that a gaydar would solve this, which suggests to me that the simulation is pretty shallow.
I think there's two different things at play here - one is the idea implied by the author that in the future homosexuals will not be a minority (or that people will not be 'straight'
by default) 'because the future', which is conceptually difficult to believe because on a completely apolitical furthering-of-the-species examination of biological imperative, any species with sexual reproduction is inherently going to favour sexual reproduction that continues the species in its population.
Even with magical future tech, you're going to be actively fighting against biological imperatives to not have biological urges based on perpetuating the species amongst the population.
Its hardwired.
Its not
insurmountable, but its still there, and its still going to be there. People still have arachnid responses.
The other thing at play is the kind of insidious notion that things in the game don't align with the authors pet theories of how things 'should be', and are then being extrapolated into the game creator making a political statement - a negative statement at that - that is not demonstrated (
and has some pretty good counter evidence) and is the kind of thing that can effortlessly ruin a reputation or business, and is honestly kind of a shitty thing to jump to in a videogame review.
Especially as the easy option would be to just not even bother trying to model any aspect of human behaviour that has any possibility of offending anyone through omission.
That Kinsey mod seems a pretty elegant solution tbh, seperating procreation from recreation / romance.
