The Right to Life---was not just about abortion----it was about preserving all life.  ABORTION became the catch word in JP II and Benedict's papacies BECAUSE abortion became more prevalent during John Paul's pontificate.  Before that time, birth-control was the big item.  On May 9, 1960, the world's first commercially produced birth-control pill, Enovid-10, was approved by the U.S. Food and Drug Administration.  After Vatican II, Pope Paul VI promulgated his encyclical "Humanae vitae" on July 25, 1968.  It was ill-received because it came during a year when there was a genuine global collapse of trust in civic and religious authority.  Paul VI never wrote another encyclical during the rest of his papacy.

Far from calling post-Vatican II popes heretics---you need to look at your own concepts.  You really don't know church history OR how church history works hand and glove with secular history.
