It is disgusting. It is everywhere. And yet nothing is done because society deems it acceptable for women to be treated as second class citizens.
Men don't acknowledge how unacceptable their behaviour is. Men don't hold each other accountable in any way for their behaviour towards women. In fact, they largely actively encourage one another in it. Why? Because there's no backlash. There's no punishment. There's no disapproval. It's just boys being boys. Lads being lads. Men have their needs. They just can't help themselves!
In addition, many women downplay, excuse and enable their behaviour (case in point - #notallmen movement). We are so conditioned to please men and to seek approval from them, that even when they abuse us, we seek to excuse them. It's so deeply depressing.
How has this happened? Well, women are depicted as sexual objects in all of our cultural outputs. From a very young age, everywhere we look, women's lives are shown to have value in proportion to how they are viewed by men.
In the vast majority of depictions of women in fiction, their storyline revolves around them seeking a male partner, seeking to hold on to a male partner, or seeking to marry a male partner. The vast majority of female conversations in fiction will be about men. The ultimate success, in society, for a woman, as depicted in all of our cultural output, is having her existence validated by having a man agree to marry her. If you don't know much about this, research the Bechdel test, which lays it all bare. Think about the shows you watch or books you read - even when a female character has a career or interest, what is the driving force behind the storyline? 99% of the time, it'll be her search for a man.
Look at the depictions of men in fiction. They're out saving the world, climbing the career ladder, and pursuing their dreams. Their romantic lives are on the periphery of their existence, and they are the ones making all the choices. Even if they treat women badly, often we are encouraged to sympathise with and excuse their behaviour. One of the most popular books taught in schools is Of Mice and Men, a book about a man with special needs who assaults and then murders a woman, who no one grieves for, because she was wearing a sexy dress and was asking for it. The tears at the end of the book are for the man who killed her.
As long as our society continues to produce cultural output across all types of media - music, film, TV, literature, video games, etc - where men are depicted as being active and women as passive, and where men have power over women through women's dependence on them for the meaning of their existence, we will continue to live in a world where men think they can treat women like animals.
These sexist attitudes are so insidious that many of us don't even notice we hold them. You don't have to be someone who shouts sexist abuse at women to be a misogynist. Any woman who has allowed herself to internalise the patriarchy to the point where getting a ring on her finger is the main driving force of her life needs to take a good look in the mirror, because she is part of the problem. Any man who says he can't wait to walk his daughter down the aisle, treating it as the expected pinnacle of her achievements as a woman, needs to take a good look in the mirror, because he is part of the problem. Any attitude that places a woman's happiness, success or achievements as being dependent on her relationship to a man perpetuates the belief that men have the right to treat women as they wish because women need men and men don't need women.
More people need to question and more people need to adapt their behaviour if anything is going to change. Passive anger isn't enough.
