How men see women

In almost 5 years of insti life, I have noticed that guys think girls are very arrogant. That the girls go to guys only when they need some help and then ditch the guys later. All around I hear stories about break-ups, friendzones, crushes, etc.. Girls have a different opinion- they think that guys are just sexual predators. The confessions page was full of this stuff. This way of thought is not limited to insti, it's the same story everywhere. Men are stereotyped as sexual predators, women are stereotyped as selfish bitches. These kinds of things interest me. I know for a fact that girls are in general not arrogant and selfish, and that sex is not the only thing in a guy's mind. So why this popular opinion?
The problem is mostly because of the way men see women. What I'm going to say next is my theory based on what I know about how men usually think. I know very little about how women think, so whatever little I write about that is just speculation. I only intend to explain the general mindset, exceptions are always present.

Before I say anything more, I must say that the bigger problem is that what people think and what they say are rarely the same. That is usually because of the fear of being judged by others. I'm sure that if a girl reads this post, she'll be like "Are all guys like this? That's really gross. Why can't you see a girl for what she is..." and all that crap. Some guys may deny that they think like this. My theory is based on the hours of discussions we guys usually have when we're joblessly having tea or gen fart about relationships, and a bit about how I think too. But then, I may be wrong or my theory applies only to the kind of people I know. Whatever it is, if you're not open to theories on such sensitive issues, I strongly recommend that you don't read the rest of the article. 

Quite often men become friends with women. That usually happens when they are involved in the same activity, like taking a common class, working together, being neighbors, etc.. I'm not talking about the kind of friendship where it doesn't really matter if the friend's a guy or a girl. What I talk about is when a guy gets "interested" in a girl without even talking to her. The interest is based on only her appearance. He may or may not know her.  Sometimes they're just acquaintances, and sometimes they're complete strangers. Whatever the case, when a guy's interested in a woman, he usually looks at her as one of these two things - 1) A potential sexual partner, 2) A transcendental beauty. How a particular guy looks at a particular girl depends on the guy.

1) A potential sexual partner
I don't have to say much about this. Guys love to have sex. We tend to think of most girls as possible sexual partners. And we find some girls to be particularly seductive. That doesn't mean we want to force them into anything. It means that, in general, we try to make things move in that direction. It also doesn't mean that we talk to a girl only to have sex with her. Sex is not the only thing in our mind, but then it is also there in our mind. We see some girl who is particularly sexy, think it'd be nice to do it with her, and then get back to the more important things in life. Just like with anything else, there will be some guys who'll be obsessed with sex and have all of their life built around that, but that's a very small fraction of the population.
We are in general not subtle, and we are also quite loud. We talk about a lot of things- politics, movies, sports, sex, policies, philosophies. Some guy would indiscreetly talk about girls he finds sexy, among a lot of other things we talk about. Girls usually pick up that single sentence, which they find extremely offensive, and stereotype guys as sexual predators. Consider a guy and  a girl who know each other quite well- they could be friends, relatives, be in a relationship or are just neighbors. Sex would always be in a guy's mind, and at some point or the other, the girl may see that. That only adds to what girls think about guys- sex is the only thing guys think about.
The fact is, we think about a lot of other things but they are not of much interest to girls. The gen things we say are mundane, nothing special, and always go unnoticed. But sex, however low priority it may be, however rarely it is talked about, catches the attention of girls and hence the perception.

2) A transcendental beauty:
I say transcendental because, for a guy, nothing else compares to the beauty of a woman- not sceneries, not paintings, not the cute faces of kids, not majestic animals, .. nothing. Sometimes guys may find some moves in sports to be very beautiful, but those things come and go. The beauty of a lady, that is something that stays in a guy's mind for a long long time. When we see a girl and find that she's gorgeous, we usually stop thinking of her as a person. All of her qualities- good or bad, are totally forgotten. She could be the rudest and the dumbest girl ever, it doesn't matter. When she's there in front of us, we think only about her beauty. When we think of her, her beauty is all we notice.
Being beautiful is not just about the color of a girl's skin, its different for different guys. Sometimes its the way she conducts herself, the way she talks or smiles or laughs or walks, the look in her eyes, sometimes its her figure, sometimes the way she dresses. Whatever it is, that is the only thing that matters to a guy. The girl's beauty is held way above everything else, we crave to see her, meet her, talk to her. Guys do all kinds of things just to be noticed by the girl, so that if she notices the guy, she may want to spend time with him.
If a beautiful girl walks by, we can do nothing but admire the beauty, we can't take our eyes off her, the world stops. That's why a lot of times guys are found just staring at girls. The girl may find it offensive, but it is meant as a compliment. Against the backdrop of the few sexual comments on some girls, this admiration of a lady's beauty is almost always seen by girls as "checking them out".
We admire a beautiful lady for a long time, forget about everything else about her, do whatever she wants us to do just so that we get to spend a little time with her. The ladies are like goddesses, not to be judged, not to be bad-mouthed, not to be embarrassed, not to be denied any kind of service, but only to be admired and worshiped. But after sometime- days or weeks or months or even years, when the guy either takes her for granted, or when he's frustrated that he doesn't get to see her anymore, or she gets a boyfriend or gets married, or he talks to his friends about something or whatever else, that guy starts to look at the girl as a person. The dream world he built around her shatters to pieces, the lady he had seen as an object of perfection is now just another person with all kinds of defects, and its hard to make peace with that. Every quality in her that he does not like, starts to hurt the guy. All her mistakes are now magnified.
Once the guy starts seeing the girl as just another person, he would think about everything he did to woo her. Instead of accepting that it was him who decided to do all that stuff to win her over, he blames the girl for being arrogant and using him. He doesn't understand why the girl did not choose him over the others, he cannot think that he may not be good enough for her. He starts comparing himself with any guy she goes out with. His ego strongly confirms to him that the other guy is just a douchebag. Like the jackal that couldn't reach the grapes, the guy ends up believing that the girl's a bitch. This happens with a lot of guys and we end up stereotyping all girls as arrogant bitches who think very high of themselves.
