I said a few years ago we're watching evolution as it happens when it comes to gender. People are exploring what gender means, and redefining it. It's evolving and adapting. Society and culture defined what gender meant, not biology. Now it's changing to fit in a new world. My prediction at the time was we would see a lot of those gender identities fall away as the stronger ones won out. I think it'll happen. Once people settle on a definition they'll start to find their place.
Once women wearing pants was unthinkable, now it's so common I'm sometimes surprised to see one in a skirt. For some reason it's harder for some to accept a man in a dress than a woman in pants. Both were seen as the fall of Western civilization. Yet, women in pants, and men in dresses are still here, and so is our civilization. It's adapting to the environment and will be stronger for it.
