Fantastic article! I love how you put in a man's perspective. As you said, feminism isn't just for women, it's for everyone, including men.
What you said about where the word feminism came from made me think. Rather than only advocating for women, it's a defence for characteristics that have traditionally been deemed "feminine" eg. being sensitive, caring, empathetic. Of course, rather than only being acceptable for one gender, these are really just neutral character traits that anyone, regardless of sex or gender should feel confident enough to have. And this, in many ways, is what feminism stands for!
