The problem isn't all in our heads. It's in society. It's in you guys saying the problem isn't real.
These aren't internal sexism issues, they're issues women have to deal with ever day of our lives. Until you've walked a day in a woman's shoes, surrounded with images of what women should be according to men, feeling the gazes of men on your body, fearing for your safety when walking alone in the afternoon because it's a real possibility that some man might come and force you to have sex with them (they censored the actual word for this action for some reason) because what are women but sex objects anyways, don't say it's all in our heads.
This is our society. This is the problem.
That seems a bit paranoid... Most women I've met have gotten around the whole "sex object" thing by not dressing provocatively, thus not attracting unwanted attention. If you don't want the attention, don't beg for it.
Yes, there are really sexists in the world, it's still a problem and always will be. But they are on both genders. The men see women as nothing more than child-bearing workhorses and sex objects, and then women see men as violent, evil testosterone-filled maniacs.
I want to see this lady's uniform changed as much as you do, but to jump to these conclusions is a bit upsetting.
