Chimamanda hit a lot of the nails on the head in this essay. While the essay is short, she seems to point out the problems with gender and explain why they don't make sense - how the past is different than the present and the future, so why do we let culture and tradition get in the way of gender freedom? She also beautifully ties in how men could also benefit from feminism, but doesn't spend the entire book arguing why.

But, it is just an essay, and I'd love to read more about it - perhaps in her other book. Its worth the read, but might leave you wanting more.
