Might help also to describe what you think feminism is, since it’s one of those terms that is overloaded.
I once had a physical therapist tell me she wasn’t a feminist because she thought women couldn’t be as physically capable as men when serving as soldiers, and seemed to believe feminism requires treating women exactly like men.
I told her I was a feminist because I believe in equal rights for men and women, an idea she did not seem so opposed to.
I am a feminist because I believe men and women should have equal rights. I think a lot of people fell for the propaganda that feminism is about women over men or something. The thing a lot of men fail to realize is that “the patriarchy” hurts them too. A lot of the things you see men complain about like being told to “man up” or not being able to express their feelings without being mocked are 100% a side effect of patriarchy.
