Heather Mac Donald labels a trend:
It is an iron-clad rule, presumably taught in journalism schools, that when discussing black single mothers and their children, one must never, ever ask: Who and where is the father, and how many fathers are there? Tens of thousands of articles have been written about the struggles of black single mothers, and the appearance of their children is always treated as a virgin birth. Not only are there no fathers in sight in such articles, there is no curiosity about where the fathers are and why they’re not stepping up to the plate. Instead, the reader will learn in great detail either about the callous lack of taxpayer-funded social services or, as in the present article on black infant mortality, about the provisions that a wise and benevolent government has made available to the mothers and their miraculously-conceived children, who seem to appear with the same inevitability as the tides.
