If some feminists include men, I’ll very gladly learn about them, because I’ve never have before. And I consider myself informed.
You are not. There is a long tradition of feminist thought that makes very clear that feminism is inclusive of men. What’s more, feminism very explicitly advocates for the betterment of men in the form of freeing them from oppressive gender roles. I suggest you check out works like Feminism Is for Everybody by bell hooks for an introduction into this pillar of feminism.
