Women's Fiction vs Fiction with a Female Protaganist

Agent Scott Egan attempts to define the genre of Women's Fiction. 

 First of all, in most cases, women's fiction is told from the point of view of a female. ...

These are stories that are looking at the world through a female lens, therefore, the need for a female protagonist.

Hm... well... okay. A lot of the fiction I read has a female MC. Some of the characters ride dragons, some fall in love with dragons, some fight on spaceships...

But that's not Women's Fiction. And Egan agrees. 

 Now, like all pieces of logic, if women's fiction is told from the point of view of a female, then every story out there with a female protagonist is women's fiction. This is false. 

 Remember, when I say we are looking at the world through a female lens, we are also looking at how the female brain is processing what she sees in the world. The main focus of these stories is to see how women think, see the world and react to things in the world. For all of you academic people out there, this is the thesis of women's fiction. If your story has a female protagonist, but the focus of the story is the thriller or mystery in the story, then we cannot classify it as women's fiction, but as a thriller or mystery.

And don't add any cool stuff, like galactic politics, Elvish factions, magic battles, bizarre hive mind aliens or telepathic squids. That would very likely move it out of the realm of Women's Fiction. Although perhaps there are a few exceptions... The Time Traveler's Wife? 

What do you think?

I usually only read Women's Fiction, where, like The Time Traveler's Wife, it includes a paranormal or speculative element. So I kinda wish that Egan had provided a more specific and detailed definition than simply to say what Women's Fiction is not. I've tried my best to restate it in the positive, but I'm probably missing some elements that distinguish the genre. 

Here's my stab at it: Women's Fiction is a story about a woman or group of women and their relationships, usually a set in the real, contemporary world, or the real past. This is in contrast to an alternate history or urban fantasy. The stories also usually have a focus on relationships. Not necessarily romantic, but although that could be a component, but a larger web of family, friends, intriguing strangers and rivals.
