[Nieninque]

I doubt women are any more "aggressive" today than they've ever been. We just have more freedoms and are able to express ourselves more due to laws made in recent years. I also don't agree with the Bible's take on men being the leaders and women being followers. There are countless spineless men who can't lead sheep let alone other people, and countless women who are strong and competant leaders.
Concerning Tolkien, he could have included a woman in the Fellowship (just to make it interesting), but I don't feel he made it all-male out of sexism. They just happened to be men. Besides, I doubt anyone would have liked a female Gimli ^.~
