It is not absurd, and you may be laughing but a lot of other people are not, including myself. All of these scenes are set up to play out the way that they do. In other words, there are plenty of artistic choices at a writer's fingertips. When the only person to shoot a phaser several times and still they need help is a woman, that says something. You can say that Spock needed her help too, but he is the one who ultimately takes Khan down in the end. No one is getting excessively outraged here, but feel free to assume that's the case.
