Re–shuffling of tweets posted an hour ago: Hugh Hefner peaked as a progressive cultural figure sometime between the late ‘50s and the mid ’60s. Hef’s brand was over by the mid to late ‘70s, but respect must be paid on the occasion of his passing. Hefner was one of the key agents (if not the key agent) in the sexual-attitude liberation of Eisenhower-era America. Playboy, Hef’s brainchild, arguably did more to loosen the strings on the straightjackets that were being worn (or more accurately submitted to) by middle-class American males than any other cultural factor, and that was no small feat. Hefner is dead, but his legend — intense, pipe-smoking, white-collar guy ignites a libidinal revolution — will never die. Only in America.
