Executive Summary: some of you were had, and might want to look up “sarcasm” in the dictionary.
In any event, the satiric point of the post was that there’s always a social cycle of decadence and morality. Social conservative and trad-con types seem to believe that pre-pill America was a uniform time of common morality and sexual continence (you could argue that feminists see an oppressive dystopia in the same uniform manner, that no woman ever had an orgasm or a job before 1960).
Even the most banal review of modern history shows the truth.
There were the booze- and sex-soaked roaring 20’s (Fitzgerald’s heydey),
the privation of the depression,
the patriotic war era,
stuffy postwar materialism,
then the societal adolescence of the 60’s,
the swinging (sexually at least) seventies,
then the decade of AIDS that shut off the spigot,
the safe sex era and “didn’t inhale.”
Now we’ve got the hookup culture and a bunch of boomer parents wringing their hands that their kids might be doing the same sexual adventuring they did in their young adult lives.
Now heaven knows, anything goes.
