I never understood that. It seemed like Kirk's girlfriend had to have a boyfriend. She tells Kirk if he wants to leave her, she's got someone lined up a a stopgap boyfriend, but then she needs to be transferred to another ship to hunt fresh game. She also says she works in a chem lab. Does she make no effort to advance in that capacity, i.e. by making poison or explosives or just by being a reliable chemist for whoever the top dog is? Does all her career advancement come from her boyfriends? Maybe it's both. Maybe people do advance by doing their job, but on the side women have boyfriends and men commit murders.And it seems very sexist - Captain's woman.
The sexism of it doesn't bother me because it's supposed it's the mirror universe where people are bad. But I was very unclear how the sluttiness fits in. What do people do when they're 50 y/o, still fully capable of doing an intellectual job like chemistry, still able to fight, but past the age of having a lot of boyfriends and girlfriends? Do they take to mother and grandmother roles, where they're supposedly honored for traditional roles maintaining the home? Maybe their goal is to get pregnant by some high-ranking person.
My point in this depressing line of thinking is that I understood how the men desired to seize power through violence, but I don't understand what Kirk's girlfriend was after.
