I shape my perception on women based on women I've actually interacted with, not what Holly Wood or Gears of Grim dark 4: BIGASS FRIES edition present.
I guarantee this isn't as simple as you think it is. Sexist stereotypes have been shown pretty much universally to increase sexist attitudes. Nobody's going to go out and think that some shallow crappy female character is real, but when, for instance, the vast majority of female characters seem to exist solely to help out a male character, that plays right into stereotypes like "The most important thing for a woman to do in her life is to find a man".
It might not convince people, but a little bit of media might make someone feel just a little better with their sexist beliefs, and when it's getting broadcast daily to the entire western world then the influence starts to add up.
What I really don't understand is why "feminists" get rectal ravaged when a "twig with two globes for a chest" shows up on screen, if I'm supposed to feel bad about my sexuality then they can go back to getting bent.
It's not men finding them attractive that's the problem. The problem is when the goal of most every female character seems to be for men to find them attractive. I mean, the things female characters get put through to look sexy are just ridiculous. If male characters are subject to
the same thing, it's comical how ridiculous they look. But when that spine breaking hey-you-need-to-see-my-ass-and-my-boobs pose is basically Zero Suit Samus' default, nobody blinks an eye.
If women's sexuality were given
as much weight as men's, it'd be fine because everyone would have something nice to look at, but currently nobody wants that.
