Thanks for the background. Presently, I'm reading William McGowan's book, Coloring the News: How Crusading for Diversity Has Corrupted American Journalism, which details how major papers (and in some cases, TV) -- in particular, the New York Times, Washington Post, and L.A. Times -- have variously ignored or misrepresented stories on race, sex, and immigration. One-third of the way through, I have not seen any discussion of photo quotas, or of the responsibility of "J-schools" for the present impasse. So, while McGowan does an excellent job of showing how the major dailies misreport big stories, the crisis runs much deeper.
That title, How Crusading for Diversity Has Corrupted American Journalism sounds like he has nailed the reality in his title.
