Even a system smart enough to figure out what was intended is not compelled to act accordingly: human beings, upon learning that natural selection ``intended" sex to be pleasurable only for purposes of reproduction, do not thereby conclude that contraceptives are abhorrent.

This seems like a distracting example that is likely to set off a lot of people's politics behavior.

For instance, it may be misread as saying that humans who don't draw that conclusion are somehow broken.
