I could see how a teenager with raging hormones could see as AL as "cool" if he interprets it as allowing him an irregular union with his girlfriend.  If a young person perceives the Church winking and nodding to adulterous second unions, why wouldn't a sexually active teenager feel justified in demanding the same deal for their fornication?

If that is what Catholic school students are getting from AL, I feel bad for the parents who are wasting their money on Catholic education. The kids could get a similar message from the public school for free.
