Post-structural feminism is an idea that tries to understand how women are treated in society. Imagine you and your friends like playing with toys. Even though you are all friends, some of your friends may always get the best toys, while others might have to play with the toys that nobody else wants. Post-structural feminism believes that women are treated similarly to the friends who have to play with the unwanted toys.
Post-structural feminism suggests that we can't just blame one person or group of people for this problem. Instead, it is a systemic issue that is built into our culture and society. Think of it as a big machine that has been running for a long time. Women have always taken a backseat in many areas of life, and this machine works to make sure things stay the same.
Another key part of post-structural feminism is looking at language. Have you ever noticed how people use different words when talking to boys and girls or how girls are often talked over in class? Post-structural feminists believe that language is used to control power and that we need to examine how it's used to help or hurt women.
To put it simply, post-structural feminism is about recognizing that women have not always had an equal place in society, and it's important to try to understand and fix this problem.
