I've recently spent a lot of time thinking about and researching the sociology and the history of ethics. Based on this I'm going to make a prediction that may be unsettling for some. At least it was unsettling for me when I made it less abstract, shifted to near mode thinking and imagined actually living in such a world. If my model proves accurate I probably eventually will.
"Between consenting adults." as the core of modern sexual morality and the limit of law is going to prove to be a poor Schelling fence.
Unsettling in what sense? Like, it will eventually erode monogamy, and so cause more sexual inequality? It will break down gender-based sexuality, effectively turning everyone bi? Legalized rape? Dogs and cats living together?
(Channeling Multiheaded: Don't be so vague, especially when you're making predictions!)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
