Yeah, removing pronouns completely is probably the best way to go.
It would also be nice to have a toggle so you can elect to have only male names generated, perhaps by category so you can have an all-male military but have civilian leaders of either sex. Sending female pilots into combat is also jarring from a roleplaying stance for those who don't envision a PC future!
Yeah, this has been asked before as well as the opposite for those playing the Syreen or something similar. Best option would be to have all male, all female, male military rest both, female military rest both options. But it would require leader name files to be gendered, which I have no idea of how difficult it would be.
