Epidemic of Outrage

A little taboo candor at Salon:

… the Phelps affair asks us to feign anger at something we know is commonplace. A nation of tabloid readers is apoplectic that Brad and Jen divorced though half of all American marriages ends the same way. A country’s fetish with family values goes ballistic over Paris Hilton but spends billions on pornography…

…our narcotic of choice is fake outrage.

Can you explain it?
