Yeah, the pews are filled with them /sarc.  My kids are like the ones you refer to.  Why?  Because my wife and I made a concerted effort to educate them, notwithstanding the efforts of their schools and teachers to make them reject the what their God and their religion teaches them.

You know which kids survive public school brainwashing best?  The Jewish kids, whose parents enroll them in Hebrew schools at early ages.  They've maintained their religion and heritage in a mostly-Christian country, some of them even holding on to ancient traditions.  

There is much the Catholics could learn from the Jews about perpetuating faith.  Number 1, they never disparage their own religion like Catholics with same-sex attraction and those who have divorced do.
