FYI, let's discuss the weird attraction that Rogue Squadron pilots have for Bothan females. I understand perfectly that sexual tastes will change in 25,000 years. Basically, human is not the only thing that individuals will go out and "dance" with. OTOH, Gavin's attraction to a Bothan is meant to be a lesson in tolerance I think. Even if, again, I veer on the side that biology would pretty much rule out most attractions.
