I am 100% imposing gender on them; that is what happens in most cases in the real world. Sometimes people are explicit about their gender, but in most situations, gender is assumed from social and cultural cues, including fashion. KSP doesn't exist in a vacuum; whilst none of the Kerbals are labeled explicitly as male or female, it doesn't take a rocket scientist to determine which is which for most of them. And in KSP2 there are very few female presenting Kerbals. We can't fix problems in representation by pretending that "gender doesn't exist" and that all these roughly androgynous but fairly masculine Kerbals can represent everybody.
Nope, I'm aware. And I know the Kerbal effect, which is why this issue is so important. I'm glad your KSP1 roaster is two-thirds female; that's awesome for KSP1. However, this is a KSP2 suggestions forum and our KSP2 roaster has been, at best, 10% female, which is the point that I'm making. Why has KSP regressed on this? What possible reason do they have for tweaking the algorithm on the ratio? I'm not suggesting some conspiracy at the developers; I'm sure it is an oversight. But it seems like one that is easy to fix.
You can argue the semantics of "gender" and the technicalities that the Kerbals don't have an explicitly assigned gender. But none of that changes the fact that my little one looked at the list of Kerbals, and she concluded that female Kerbals can't be Kerbonauts. Obviously, this is anecdotal, and I care more because it was my kid, but I'd be very surprised if she were the only one that landed here.
I understand the devs have a long list of more important problems to fix right now. But to my 5-year-old, this is more important than the terrible maneuver nodes or the Kraken consuming our rocket (which, with the attached mythos of "the Kraken" seems more of a feature than a bug as far as she is concerned). I'm not trying to create moral outrage about this or suggesting I'd boycott the game because of it*, I'm simply forwarding feedback in the suggestions forum. If this game lasts as long and has as much of a profound impact as the first one, the views of her demographic are not only valid but important. And I'd wager rarely heard on feedback channels.
*My current workaround is intentionally launching male Kerbals to their deaths until the generated roaster is more representative. I'm undecided as to whether this is brutal or an appropriately Kerbal solution to the problem.
