1968 was a loss of innocence. While some know of the dysfunctional asexuality of Catholic sexual teaching, most ignored it. Vatican II openend up the gates of free thinking because it changed so much. People no longer feared damnnation as a result of disobedience, which was unhealthy anyway. Humanae Vitae sealed the deal. Repudiate it, especially the sexual orthodoxy, and people will flock back to the Church. Also, more afternoon Masses on Sunday. People work too hard to have to get up Sunday morning.
