I did my undergrad at Oxford in English, and thus the subject was generally rife with insecure mansplainers shouting their opinions louder then the female students in their classes, but one particularly egregious example comes to mind.
In a class with two other students (one male, one female) and a female tutor, we were discussing a famous Jacobean revenge tragedy, in which the female protagonist bribes her father’s “deformed” male servant into murdering her fiancé so she can marry someone younger and better-looking, in exchange for her virginity. Said female character then continues to have sex with the male servant for the rest of the play, until eventually she gets caught out by her lies and stabbed because, well, it’s a Jacobean revenge tragedy. Dramatically, it’s a great play; in terms of feminist critique, it’s problematic.
In the class discussion, I was outlining my view that there was a lot of coded male fear of female sexuality embedded into the environment and settings of the play (dark, tight spaces, secret tunnels etc) and that the playwright only allowed the female protagonist to work through male agents, which she was then punished for anyway (with a nasty reference to the Biblical Eve being the downfall of mankind, as well as the aforementioned stabbing). I was then interrupted by the male undergrad - the only male in the room - telling me how I’d got it wrong because the female protagonist was, in fact, a ‘feminist character’.
Discussion was a major part of the class so I let him talk, despite being interrupted. He then mansplained to me how I was “interpreting feminism wrong” and that the female protagonist of the play was, in fact, a feminist because she “went out and got what she wanted”, despite a) having known me for two years and that I was actively involved in the feminist movement and b) it was evident that in the play the female protagonist neither “went out” OR “got what she wanted”.
My response was to puncture this with the question, “She has her fiancé murdered because she doesn’t fancy him. Really. Is that what you think feminists DO?”
Our tutor - whose specialist area was feminist critiques of 16th and 17th century drama - applauded.
