No, I'd disagree. There are significant differences between men and women, some of which are innate but more of which arise in cultural environments and social expectations. Sure, a scene with men having a conversation may be similar to a scene with women having a conversation, but a story about a man is vastly different from a story about a woman. I would like to write about more female characters, myself, and every time I start a story I think to myself, "Would this story work the way I wanted it to if the main character were female instead of male?" Unfortunately, the answer is usually no.
