My thoughts: Having been a young woman raising my family during the 1970s and a faithful church-going person, I recall the explosive 1970s with the rebellious hippy movement, anti-establishment, anti-war (Vietnam), make-love-not-war, loud, protesting, drug-induced-stupor that exploded around us. Compound this by living in a small town whose main function was the support of a large state-owned university, it was very much in-your-face around us.
I remember, too, that a new "form" of worship and singing (not traditional hymnology) began to emerge that rattled traditional worshipers sensibilities.
