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.
Feminism as a movement specifically sheds light on the systemic violence against women and gender-diverse individuals under patriarchy. That doesn’t mean men don’t also benefit, but it does shed light on the primary issue.
