Hm, equality is precisely what I think feminism is about, some of the most famous feminist works like bell hooks' Feminism is For Everybody is entirely about how feminism is an egalitarian movement.
What do you expect feminism to expand to, and why do you think that? It's interesting you feel like you might not know much about feminism - have you read or studied any feminist authors or books (like Simone de Beauvoir's Second Sex)? What has informed your view of what feminism is?
