They're both (arguably) existential threats. It's just that only one of them can be (and is--constantly) publicly acknowledged, while the other, apparently, can't be. Quoting John Derbyshire on the graph from the first link: > That graph—the world’s most important graph—looms over the 21st century like a monstrous great crow. Yet we can’t talk about it. Or rather, I can, and Mark can; but no-one with much more of a profile than us, can. > Why not? Do you need to ask? That line shooting up on the graph represents Africa—black people (mostly), and a high proportion of them Muslims. The other line, the one plodding along horizontally, represents Europe—white people (mostly), and a very high proportion not Muslims. > In the state ideologies of the Western world, black people are sacred objects to whom whites must defer, Muslims only slightly less so. Nothing negative may be said about these peoples, nor even hinted.
