The reason why there is such a divide sometimes in feminism is because words like patriarchy conjure up some kind of secret conspiracy. Whereas the word chauvinism, which is essentially the same, not so much.
Patriarchy, oppression, liberation, as concepts are entirely understandable in the context of the history of women's rights and the academic study attached to them.
But they fire people up. Whereas words like chauvinism, sexism, freedom from stereotypical gender roles, sounds much more accessible. But they essentially mean exactly the same.
The concept of what is sometimes called Liberal Feminism tends to mean that women's choices are valid purely because they are a choice. Something has been denied women for centuries. The freedom to be able to make your own decisions, on your own terms.
The slight disconnect arises when you apply radical/4th wave feminism. But only because they put the framework of 'choices' into an historical context.
So the disagreement might arise over, say prostitution.
Liberal feminists will see it is a woman's choice to do what she wants with her body and that she has full body autonomy to make her own decisions.
Radical feminism will see as a commodification of women, historically something that disadvantaged women, and of only real benefit to the customers (men).
The fact that women make money from it, is criticised, not because they are earning a salary from selling their bodies, but that there should be other options available to women so they don't have to resort to it. That it is controlled by, driven by and of benefit to men, not women.
There often then follows a bit of a bunfight about people who know high class/happy hookers who love their jobs, and other people saying how can you love a job where you have a panic button in the room and have to have sex with a stream of grubby strangers.
So most of the disagreements come about because making a choice is deemed feminist and necessary, but some choices have knock on effects. But sometimes only if you see it in a wider context and with an historical perspective.
It really goes down the drain when people talk about stay at home mums.
The truth is, we live in a, and I'm going to say it, patriarchal society.
Some people actively don't want to swim upstream, others do as best they can and don't always succeed, and many don't notice that the stream is flowing in the wrong direction.
But whether you agree with it or not, feminism will, has, and continues to open up the world for women. To protect women's rights to biological autonomy, to give them as much chance as they can to succeed in a world that is often stacked against them. To insist that unpaid work like raising children and house work is valued more than it is. Because it's ludicrous to that half the population do one of the most important jobs mankind has been given, but it's so undervalued. Whilst the other half to get to make all the decisions about the world is run. Including those that directly affect the first half.
Feminism is for women, about women and by women.
There is nothing weak about conceding points, acknowledging difficulties and appreciating situations.
And the ironic thing is men will benefit from feminism every bit as much as women.
