You can’t lose what you never had.

The “West” is a rather broad statement. This would be as opposed to the post WW-II era I assume?
Their was a teaching process which begin to lack in the 60’s and in the 70’s do to the parents and the teenagers refusal to cooperate. History outlines in pretty well. The compromise came when children received communion which in many regards as with Jewish tradition is a right of passage. Many parent’s made the mistake of allowing their children to discontinue Mass etc. There childrens, children in many case’s never bothered taking their children to Church, Sacrements etc. Thus the resulting generations really have no real understanding. Protestant, Islam, Mormans compound the issue. Buddism become a fad through transendental meditation.
Of couse this isn’t with all Catholics. The Bible was assumed during this period of being a Fairy Tale till Archaeological evidence supporting it arrived, God was banned in schools. abortion became legal 62-73. The country was in a state of protest over War/Freedom and Civil Rights. Children were traumatized by Vietnam bought live daily on Color TV in all its magnitude. American lost some great leaders is a short period of time. There’s a long list. By 69 Peace pretty much turned to murder, drugs, crime. And the domino effect came into play.
Alfred the Great summed it up well, “Remember the evil that befell us, when men stopped learning, and stopped teaching each other.”
There’s a very long list of heresy today which includes just about every one since 1-AD. Add the atheism, communism, secularism, relativism, materialistic aspects of more modern society, and a vacuum is created. And what happens with a vacuum? It must be filled with something else as the laws of physics state. At the moment with strident clamor this appears to be Islam.
It goes on and on, none pretty. There’s hope and faith is not dead. However it will take a very big effort to teach and speak up. Its called each one, teach one. Teaching must be done through love and state of actual care, but firmly. You have a chance to vote for Pro-Life, Relgious Freedom in 2012 etc. However, I still “Catholic’s” who seem to think this is acceptable.

You have to ask yourself, what am I doing to correct this problem?
The church plays no fault in the above process. That is a falacy and assumption, which is based on no fact. All the Popes since Pius XII have responded correctly.
Peace.
