I blame parents for most of the women's problems. Everybody gets prejudiced against, but men overcome prejudice more often sons they're taught not to take shit from anybody while daughters are taught to be meek.
I agree, to a certain extent.
However, I remember back in my high school, a lot of the girls who were independent and stood up for themselves would be labelled "bitches", unless they were attractive, in which case they would be called "stuck-up bitches" or "ice queens" or something equally stupid. Girls who were in a lot of relationships would be considered "dirty" or "sluts", and girls who were never in relationships were thought to have serious mental or emotional issues. We had plenty of pregnancies, too, and the girls who got pregnant were ostracized for being "retarded whores".
My class schedule was mostly AP classes and such, so I didn't actually see a whole lot of this go down (because the assholes that were doing most of it were not in AP classes), and most of my knowledge of the labels that women were getting were from the gossip that spreads like wildfire in most high-school settings. A lot of them originated from or were spread by other women, too, which blew my mind more than the actual sexist banter from men.
A memory that sticks out in my head was during study hall, in one of my freshman quarters before I began avoiding study hall. (I usually tried not to have one because they were extremely unpleasant) A quiet, studious girl was working on homework or something, minding her own business, and some group of guys started flicking stuff at her, somehow managing to not get spotted by the teacher who was supposed to be keeping order. This kept up for about 10 minutes and the girl was doing a really good job of ignoring it until she turned to tell them to stop and was met with condescending chortles at which point they began pelting her with spitballs. She got hugely upset and went to tell the teacher. She showed him the spitballs and the teacher believed her, probably because she was on the verge of tears. He sent the little gang of assholes to the principal's office, but they gave her some pretty threatening gestures as they were led out.
I really hope nothing happened to that girl. Looking back on it I should have done something about that, even just talk to her and try to make her feel better, but I was a cowardly freshman at the time and didn't want to risk jumping in the asshole crossfire. As I recall everyone around also just kind of ignored her. Regrets...
tl;dr: Women were really treated like shit in my high school, and the ones who stuck up for themselves were a lot of times treated worse than the passive ones. And yeah, the student body president was usually female, but with that came the snide remarks of "I wonder how many dicks she had to suck" and related bullshit.
I guess the cheerleaders and really popular girls got away without too much real direct hatred, but then they had to deal with the stereotypes of being popular or being cheerleaders, typically related to how much they are seen to 'put out'. I also remember most of the girls who did really well academically would be accused through gossip of having sex with the teachers, especially if they were blonde.
If I had been born a girl, I would have opted for homeschooling...
