Here is a recipe for misogyny:
(1) Believe that engaging in lustful thoughts is a grievous soul-endangering sin.
(2) Believe that women have a moral responsibility to prevent men fron engaging in lustful thoughts about them.
This recipe for misogyny happens to be the theoretical basis for the modern Christian "modesty" movement. This kind of attitude is liable to cause downright hatred of women because young (and not-so-young) heterosexual men are, by nature, going to be "tormented" by lustful thoughts about women all the time and they are naturally going to turn their frustration at this state of affairs upon the women who inspire this lust.
We see the seeds of this kind of misogyny in the comments of some young men who hold the beliefs described above:
“Each and every day is a battle—a battle against my sin, a battle against temptation, a battle against my depraved mind. Every morning I have to cry out for mercy, strength, and a renewed conviction to flee youthful lusts. The Spirit is faithful to bring me the renewal I need to prepare me to do war against my sin, yet the temptation still exists.
Sometimes, when I see a girl provocatively dressed, I’ll say to myself, ‘She probably doesn’t know that a hundred and one guys are going to devour her in their minds today. But then again, maybe she does.’ To be honest, I don’t know the truth—the truth of why she chooses to dress the way she does. All I know is that the way she presents herself to the world is bait for my sinful mind to latch onto and I need to avoid it at all costs.
For the most part, the church serves as a sanctuary from the continual barrage of temptation towards sin. However, the church’s members are not free from sin yet, and there are girls both ignorant and knowledgeable of men’s sinful tendencies. I must confess that even church can have several mines scattered about.”
“The one place where I might think I wouldn’t have to face as much temptation is at church, but this is not always the case. When ladies whom I’m friends with dress immodestly, it definitely has a negative effect on our friendship. When a woman dresses immodestly it makes it difficult to see her as a sister in Christ. There is a constant battle going on as I’m talking with her. Communication becomes more difficult as I’m trying to listen to her, because I’m trying to fight temptation.”
This is pretty much the same attitude early church father Tertullian expressed when he said, "Dear sisters, you are the devil's gateway...you are she who persuaded him whom the devil did not dare attack. Do you know that every one of you is an Eve?"
Frankly, if evil thoughts are in and of themselves damaging as Christians believe, or if they are likely a prelude to evil actions, then I would ten times rather have a man say to himself, "Hey, a roll in the hay with Happy might be kind of fun," than to think, "Happy is such a dirty little whore, she's the devil's gateway."
I have nothing against modest dress at all. In fact, I tend towards modest dress myself. But I view it as a matter of good etiquette rather than a moral imperative, and more importantly, I think the men around me hold the same view. It's not polite to show a lot of thigh in the workplace or at church because it draws needless attention to attirbutes that are irrelevant to the mission of one's office or one's place of worship. The beach or a nightclub, however, are a different matter, but by all means, cover up even at those places if you are not comfortable showing a lot of skin. The problem however comes from viewing modesty in women as a moral imperative and placing responsibility on women for reining in men's lust.
The other pernicious aspect of this modern Christian modesty movement is -- where does one draw the line? Randy young men are inclined to feel lust at even the slightest "provocation." Even if I am covered in loose material from neck to ankle, a sexually imaginative young man (and trust me, they're pretty much all sexually imaginative) is still going to have a pretty good idea of my general build. Even the sight of a finely turned ankle, a pretty face, or some luxuriant hair is likely to inspire a good amount of l-u-s-t.
Chances are, if you are female and not some kind of hideous swamp creature, you are at some point or another going to inspire some sexual thoughts in the men around you despite your best efforts. There's nothing you can do to prevent it. Even if you wear a burka, men are going to think about what is underneath the burka. Groups like the Taliban understand this and thus not only imposed the burka on women but also restricted women's ability to leave the house -- or even to talk or laugh in the presence of men. These inhumane restrictions on women were inspired by precisely the same reasoning as that outlined above.
The bottom line is that women cause lust just by BEING. Anti-lust attitudes -- or certainly attitudes that place responsibility on women for causing lust -- are thus inherently anti-woman, and a very dangerous strain in our culture.
