I seem to vaguely recall a novel in which a world government had declared that in order to promote hybrid vigor and resistance to disease, same-race marriages and matings should be considered equivalent to incest. People who were not already mixed-race were permitted to marry or have children only with a partner of a different racial background.
The slightly-secret reason for this was to prevent future outbreaks of racial violence by blending the races. Although everyone in the story's present day was opposed to racism, it might come back in the future. (I'm guessing the novel was written in the '60s or '70s.)
And the real reason for it was to reduce population, since most people were still System-1 racist even though they were System-2 anti-racist. Making the only socially acceptable partners be ones of other races meant that people were overall less likely to find partners and have children.
This thread is intended to provide a space for 'crazy' ideas. Ideas that spontaneously come to mind (and feel great), ideas you long wanted to tell but never found the place and time for and also for ideas you think should be obvious and simple - but nobody ever mentions them.
This thread itself is such an idea. Or rather the tangent of such an idea which I post below as a seed for this thread.
Rules for this thread:
If this should become a regular thread I suggest the following :
