Is the future of Europe an Islamic one?
This article suggests so, pointing at declining birth rates and the need for immigration (which would come from Islamic countries), and makes dark allusions to Gibbon's
Decline and Fall and hypothetical histories in which Muslims conquered Europe. Though it seems to equate European culture with Christianity (whose relevance has been declining there over the past few centuries), rather than post-Enlightenment modernism and liberalism. (via MeFi)
