Contraception Among Catholics Widespread Due to Lack of Preaching...No Kidding!

Catholic News Agency reports here about a recently published book linking the widespread use of contraception among Catholics to the the silence of priests presenting Church teachings on the subject.  I read this headline Vatican analyst: Catholic use of contraception linked to silence of clergy and said, "Hey, no kidding".  Than I thought, what other earth-shattering headlines could I come up with: Loss of the Sense of Sin among Catholics linked to Silence of Clergy.  How about this one: Empty Confessionals linked to Silence of Clergy.  Or this: Support for Same-Sex Marriage among Catholics linked to Silence of Clergy.  This: Ignorance of Catholic Doctrine among Catholics linked to Silence of Clergy.  Somebody stop me anytime.
