And David Marcus was born years before Kirk met Edith. Do you really think that if Kirk slipped up on his safe-sex practices once, he'd be foolish enough to let it happen again?
Yes. Because it happens to the best of men. It wouldn't be a
risk worth taking in the circumstance Kirk was in, and therefore extremely out of character.
It is extremely offensive and misogynistic to refer to a sexually active woman as a "whore." By using such hate speech, you've just proven that you're incapable of discussing sexuality in an adult manner, so you have no business accusing anyone else of immaturity.
Hate speech? Oh please. I didn't realize I was dealing with the thought gestapo in here, and I'm ashamed of
any writer that would subscribe to such tyranny.
Anyway, In the 1930s, anyone who was
caught having sex out of marriage wore that label, or 'slut'... or 'hussie', if you prefer. By 1929, the 'flappers' were not only completely out of fashion, but were public symbols of embarassment.
Besides, you're the one saying that someone who is portrayed as a walking embodiment of female virtue
must have sex with someone she finds attractive to be believable, even if her character is established
otherwise. Who's the mysogynist here? Who's the one reducing Edith Keeler, a clearly very conservative, God-Fearing, spirit of morality and visionary, to her naughty bits because it's impossible she wouldn't want a good screwing?
And, again, the episode
itself indicated that Keeler was a 'wait until married' type anyway
regardless of the other mores of the time. That's why it was out of character for them both.
