Why "Feminism" and not "Egalitarianism"?

I am going to send you to another blog (in Spanish) because it is really well explained why the Feminism is called like that and not Egalitarianism, because it is a really common question which has to be explained. It also explained a little more extended the origins of the term that we talked a bit about in the previous post. Hope you like it, guys.
