Corporal Punishment in the Sixties2

Fathers even in the late sixties would have intended to discipline daughters in the way they always had

i.e. by putting them over their knees and smacking their bottoms,

but how this archaic disciplinary method have been possible when applied to a sexually liberated, sixteen-year-old anti-war activist, pot-smoking hippy chick?

Was there a change in the disciplinary climate in the home and at school where the old-fashioned ‘smacked bottom’ suddenly seemed inappropriate?
