When I went back to school in '70 after VN, one of the first books we were instructed to read in some required course was 'The Population Bomb' by Paul Erlich(sp?)
I distinctly remember how anyone in class who considered a family of more than 2.3 children was absolutely pounded publicly. It was considered completely irresponsible and outright selfishness to consider more.
Meanwhile everyone was encouraged to turn their back on those old-fashioned Puritan values, and break loose to 'Love The One You're With'.
If your hippy-chick/girlfriend happened to turn up PG it was either 'her problem', or if you were a nice enough guy, you helped share in the nominal fee for an abortion.
Because of God's Grace I have asked for, and received His comfort and forgiveness .... but I did buy into many of the liberal lies back then.
