This is a bit much. Arts & Letters Daily writes,

"Americans have been made into permanent adolescents, scared of death, sex, old age." Dwight Macdonald wrote it in 1950, but it still rings oddly true...

then links to this review about Macdonald with this context:

Here is a prophecy he dashed off when corresponding with his Italian friend Nicola Chiaromonte: "If the United States doesn't or cannot change its mass culture...it will lose the war against the USSR. Americans have been made into permanent adolescents...scared of death, sex, old age." He feared a crushing American defeat in countries where "the mere struggle for existence is important and where some of the people are grown-ups." Simply change "the USSR" to "Islam," and that passage becomes as hideously pertinent now as ever. It dates from 1950, when the very dream of Hugh Hefner's and Rupert Murdoch's global pornocracies was still just a cloud no bigger than an onanist's hand.

Sorry, Dwight, the USSR didn't make it, and I don't believe US mass culture has substantially changed in the direction you'd have hoped. So what do the reviewer and the Arts & Letters Daily staff do? "Simply change 'the USSR to 'Islam.'" What? Since the argument didn't apply in the case of one enemy, we'll just apply it to another. Somebody's dislike of popular American culture is leading them astray.
