Because that’s the bargain we accept in exchange for rampant stolen valor.
In the real world, women shrink away from virtually all danger.
Women flee war while their men are conscripted to die.
Female cops wait for male police officers to handle the violent criminals.
Women rely on men to fight fires and rescue people.
Women enjoy the cushy office jobs while men build and maintain all of the infrastructure.
So when you watch or play or read some piece of media that features a 50/50 split with women occupying all of these dangerous and heroic roles - which they virtually never occupy in real life - it’s just dishonest and retarded. It’s a false experience that doesn’t map into our observable reality.
We can tolerate this nonsense if and only if the female characters involved are idealized. Are they nice to look at? Are they pleasant to interact with or read? If yes, then maybe we suspend disbelief and try to have some fun. That’s why men don’t object to hot, agreeable Mary Sues.
But the moment these liars are also made to be ugly bitchy feminists, there’s no motivation for us to continue suspending our disbelief. You’re an unrealistic girl boss and butt ugly and an asshole? Gee, where do I sign up?
I think the attractiveness is part of the story then. We must accept the logic that a beautiful woman who has fought for years can weld a giant sword. The logic allows it to a level of disconnect from reality. Sort of like Scooby Doo makes it obvious that reality should not be fully accepted because the dog can read and talk.
I made the realization while watching Sky Captain and thinking a world war II light attack plane could take on a giant robot. Then realized I was trying to place logic on a giant robot.
