How Men vs Women Write Feminist Novels

When reading a feminist novel, or one based on that movement, if differentiates greatly between the gender of the author. Women, I find, speak more passionately about the subject, and are willing to stand up and ridicule the opposite sex with great meaning and intention. However, when a man is writing a book about feminism, it's through an entirely new set of eyes. He may or may not judge the patriarchy as harshly or express similar views, even though it's the same concept.
