Edward, please educate yourself. Sexism is a form of oppression.
“If you think of it in the form of a hierarchy, you’ll see that yes, all people can experience stereotyping (assumptions that all people in one group are similar), prejudice (dislike toward a group based on those stereotypes), and discrimination (refusing access to resources based on that prejudice). However, only oppressed people experience all of that and institutionalized violence and systematic erasure.”
Men as a group do not face the same kind of systemic oppression that women face, in the same way that white people do not face systemic oppression in the same way that black people do, which is why “reverse racism” is not a thing. Oppression is experienced when a dominant group has the power to define reality.
