I started thinking about gender and how it's an arbitrary thing if you're born with an XX or XY chromosome, but it can determine your experience of the world. It's about whether you are physically intimidating vs. being physically intimidated. It determines whether you are the one to take an active role in sex and society.
I will never apologize for saying that the future of humanity and the future of the world is going to be defined by what we have in common as opposed to those things that separate us and ultimately lead us into conflict.
The traveler has to knock at every alien door to come to his own, and one has to wander through all the outer worlds to reach the innermost shrine at the end.
