My take on it is that we live in a male supremacist culture which doesn't actually recognise that it is male supremacist because it is so normalised and internalised and it genuinely believes that although we all used to be terribly sexist, everyone's equal now. Women have made enormous gains in the last century or so but every single gain has been followed by a backlash and we still haven't achieved liberation. The only way we can, is if our society stops being male supremacist.
By that I mean the normal assumption that "man is the measure of all things". That man is the default human and woman is "other". Men's stuff is seen as stuff, whereas women's stuff is seen as women's stuff. For example if you are in a serious car accident, you are 50% more likely to die than a man in a similar accident in a similar car because the average car is designed for an average man - not an average person, an average man. Because men are people, but women are women.
In the police force, there used to be a height restriction which was set at a level that most men could reach and most women couldn't and many people genuinely thought that was fair and equal, because if women couldn't achieve the average height men could, it meant that they didn't have the right to be in the force - because the force was designed for people who were men, not people who were men and women and it took them ages to realise the structural unfairness, of demanding that women be like men, instead of being like women. No institution has ever demanded that men adapt to women's norms but most institutions demand that women adapt to men's norms and if they can't, it doesn't prove that the norm is wrong, it proves that women can't hack it.
Until very recently, the British Heart Foundation has been giving our population advice about how to spot a heart attack which is totally inaccurate for women. Everyone knows what a heart attack looks like - except they don't, they know what a heart attack looks like for a man. When women have heart attack symptoms, they present very differently from men - not usually chest and arm pains. As a result of this, women having heart attacks are far less likely to survive them than men, purely and simply because they're less likely to be diagnosed in time to save their lives. Because they aren't men and their bodies aren't showing the same symptoms most men's bodies do.
That's what I mean about men being considered the default human. The world and pretty much all its institutions (except female-only ones) are designed for men and women are expected to slot into them on the same basis as men do. So when women do things men don't do - like having babies and taking maternity leave - that behaviour is seen as aberrant as it doesn't fit into the norm. The norm being, what men do.
My version of feminism is about changing the world and its institutions so that they are designed to fit the whole of humanity, not just half the species. I don't want to be equal in an unequal set up, because that means that I will always be playing on an uneven playing field. There won't be real equality until we equalise the playing field.
