Shame on them. That's just an easy out, and they really have no business having children, if they can't take the time to try to figure out basic faith and morals. "Baa, baa, let the priests tell us!" That ideology may have worked 1,000 years ago, but it now longer applies. Not now, not after Vatican II. People need to use their brains and think of what falls in line with Catholic tradition.
On this issue, although I have formed my conscience, we do have different Traditional priests (and groups) holding slightly different opinions on the subject. Until the vacuum of Church authority caused by the Vatican II collapse, it was never expected for lay people to be theologians. If they asked their confessors, and they told them something, unless they knew otherwise, they would do no wrong in simply following the advice, which, if it happened to be wrong, was on the priest. That's why it's so important for priests to be properly trained and not enough for them to be pious. It's a terrible lack of charity to ordain an ignorant priest, because in so doing you're endangering THEIR souls.
