I believe if Earth becomes one culture, then it would make more sense to treat other socially developed planets as different cultures in a similar way that we see different countries. Wishful thinking other states.
Now, what would the effect be if...the sexual heicharchy were decimated and everyone was a futanari hermaphrodite, and the concept of relationships ceased to exist so everyone can fuck anybody. And don't say family because everyone would be synthetically grown from a facility and raised by AI robots.
See you in goon heaven.🖖
