Good analysis. How does this attrition rate compare to decrease in the numbers of practicing Catholics? Meaning, if the challenge to make the faith appealing to children of mixed marriages similar to that of keeping people in the faith? If people grow up with an acceptable alternative to Catholicism - rather than being "indoctrinated" by parents who guilt trip you, it appears that the preferred alternative is to leave. The pastoral suggestion to pay "special attention needs to be paid by the church to children of mixed marriages so that Catholicism is presented in an attractive way that does not alienate the child by belittling.." should be applied to all children, and the disgraceful but deeply rooted practice to belittle any deviation from the "mainstream" should forever be abandoned.
