I Love Interspecies Relationships Sm - Tumblr Posts
So in DS9, the very first day Sisko arrives at the station, before meeting Kira, he is told "have you ever met a Bajoran woman?" and then kind of explained that they have a very strong character in what humans perceive as aggressive way.
We do not meet many Bajoran women as deeply as Kira, but some we meet sometimes fit her "no fucks found" attitude. Even Leeta, while more cheerful and naive looking, has a strong character and doesn't put up with bullshit. She may look more "girly" to humans (boyish to Bajoran?), but she still runs low on fucks.
Now, Kira's boyfriends that we meet tend to be calm, compassionate and caring in a way some human men are, but may not be perceived as very masculine.
So, culturally, we could say that "feminine Bajoran women" are more masculine to humans and "masculine Bajoran men" are more feminine to humans.
And then Ferengi, who are like an exaggerated old school version of how humans are.
In all this, we have Rom. Ferengi think he is a lesser man (=less masculine) because he doesn't know how to make profit (a trait that has been insisted to be "male"). He is insecure and shy. He doesn't even walk with the same allure as the other ferengi men, including his son. And he starts a revolution by forming a union as maybe the only masculine trait of showing character and trying to be in control of a group of people. Something clearly against Ferengi's rules and customs.
And Leeta, who is maybe a bit queer to Bajoran eyes is attracted to this maybe a bit queer Ferengi. This maybe a bit masculine Bajoran girl is attracted to this maybe a bit feminine Ferengi boy. And then he does the very masculine Bajoran/feminine Ferengi thing of caring for others with the strike.
They really were meant for each other.
