First and foremost, I’d like to start with the caveat that feminism per se is not flawed. I am specifically talking about Western feminism.
Western Feminism is based on the false notion that the main struggle in society is male vs. female. It’s easy to understand how this ideology took shape when we look at the founders and sustainers of Western Feminism - a group of (mostly) women whose only form of oppression has been experienced because of gender. But this is not true for the majority of the world, where the main struggles are often those of economic class, race, tribe, caste, religious identity, political identity, and so forth. In short, if you believe a Sikh woman living in New York City is only oppressed by her gender, then you’re off your rocker.
