pinji, plibu, cinse and other words are available. The gender-specific
words are useful for medical professionals.
I'm aware that this strive for extreme "political correctness" might
seem off-putting to some. If so, look at it as an art experiment.
There's no offense intended.
And Lojban does, in fact, have the terminology available to be perfectly
politically-correct, even if a few potentially politically-incorrect
gismu are present. None of the core language implies gender, just
several gismu. If these offend you, don't include it when you circulate
Lojban. If they're enough of an issue for you to present perfectly
politically-correct documents, I'm sure the community wouldn't be
terribly offended. Problem solved. ;)
