EY has publicly posted material that is intended to provoke thought on the possibility of legalizing rape

This looks like a complete misinterpretation, albeit one I've seen several times. The context of this is the novella Three Worlds Collide. (Spoilers follow). In that story humans meet two races of aliens with incompatible values, the babyeaters and the superhappies. The superhappies demand to modify human values to be more compatible with their own; and the author's perspective is that this would be a very bad thing, worth sacrificing billions of lives to prevent. This is the focus of the story.

Then we find out that in this universe, rape has been legalized, and it's only a little more than a throwaway remark. What are we to make of this? Well, it's a concrete example of why changing human values would be bad. Which, given the overall story, seems like the obvious intended interpretation. But hey, male author mentioning rape - let's all be offended! His condemnation of it wasn't strong enough!
