Maybe in some places Muslims and Morons will prevent collapse. Just maybe, though, as many factors can prevent that. In other places, like China and Japan, I don't find it likely at all that Muslims or Mormons will be allowed to do so. Still, given enough time, genes will adapt to the new pressures of female choice and birth control. That could be a few hundred years (at most) for genes already present in the gene pool, or a few thousand if mutations are needed.
