Since Genly Ai does come from a similar planet as us, i.e. Earth, it's human nature to have a mind state in which we like to make visible distinctions between people. That is, of course, the male and female distinction in which Genly has a hard time adjusting to when it comes to Gethenian culture. As we all know, for majority of the time that Gethenians are not in the state of "kemmering", they really do not have a gender that visibly consumes their identity. Therefore, the idea of sexism, femininity, or male dominance doesn't really exist on planet Gethen because of that. So in that case, it is very easy to understand the perspective of Genly because, just like us, he's also from a planet similar to earth. Of course, on earth, the way we act when we first meet someone, stems from appearance, and those appearances stem from race, attractiveness, and obviously gender. So the idea of visiting a planet where none of that exists, I would imagine, befuddles Genly. Like the situation with Estraven, in which he exhibits some feminine and masculine characteristics, it is definitely interesting how Gethenians live as compared to us. It seems as if all of their problems when it comes to sexism, is solved and that Gethenians can experience both sides of the male and female gender during kemmering. So ultimately, Genly's struggle orginiates from the gender distinctions he has on his planet, and that is then reflected through his inability to fully understand the inhabitants of Gethen.
