Are you proud to be a feminist? We hope so! But how well do you know the theories and ideas behind the movement? What's your stance on gender, what does it mean, and should it even exist? Taking this Crash Course Sociology clip as our reference, we have rounded up some definitions and theories to get your teeth into. You may be well-versed in theories of gender already, but if you're maybe not quite so clued up, we won't judge you, and we hope you might find the video as insightful as we did.
