What is the best literature that feminism has to offer? I think the whole thing is bullshit in the 21st century in the West but I want to give it a go.
Your post is vague.
What do you want? Protofeminism? Postfeminism? Just feminism? You can't just ask that and expect a serious reply. That's like asking what's the best book on Enlightenment during the Renassaince, there's a shitload of categories.
