Why is catechesis so bad?

Today is the optional memorial of St Angela Merici. When I said morning prayer at the hideously early hour of 11.30 this morning, I decided to celebrate the memorial. I don't see how it is better not to celebrate an optional memorial, generally speaking.

Anyway, I am wondering, why is the catechesis of Catholics so bad? Why do Catholics neither know the first thing about their religion, nor understand the reasons behind what they believe? Why do persons one supposes to be perfectly good Catholics propose absurdities that contradict right reason?

They propose absurdities that contradict right reason because they do not know anything about their religion; they do not know anything about their religion because they have not been taught; they have not been taught, or they have been taught badly, because somebody, somewhere, at some point in time, does not or did not want them to be taught Catholicism; they do not understand the reasons because they do not make any effort to use their intellects properly. It is still neither extremely difficult nor impossible to commit a mortal sin; hell still exists; states still have a right to inflict capital punishment for capital crimes, and this is an infallible teaching of the ordinary universal magisterium; women still cannot receive the Sacrament of Orders, which is also an infallible teaching of the ordinary universal magisterium; it is still necessary to pray in order to be saved; it is still necessary to be Catholic; and it is still necessary to study the Faith, or you will certainly lose it, and, having lost it, are hardly like to get it back again.

It is not a surprise that non-Catholics are unfamiliar with Catholicism.

But it is depressing when Catholics everywhere show every sign of being non-Catholics, and raise the same objections against their own religion that were raised by Protestants in the sixteenth century.
