Even universities like SU have *learning communities* in their dorms that allow for students to avoid a lot of exposure to the typical life of debauchery that most students live.
It's the student's choice, when it gets down to it. The kid raised knowing who he is, what he believes, and WHY he believes it, is far less likely to get sucked in to the hook up, party culture where ever he goes.
Not to mention, that even at SU, there are a large number of Christian and Catholic campus religious groups which are very active and working together. They, along with Fellowship of Christian Athletes, are having quite an impact on the campus. There's a huge outreach going on there now.
Some of SU's latest big name athletes are quite serious about their faith and it's widely known.
My son had a couple of football recruiting visits at ‘Cuse and at the summer football camp, he got a linebackers coach who was quite foul mouthed, bordering on abuse. This was during the Robinson era and it’s a good thing ‘Cuse jettisoned him!
I’m a Catholic and my wife is Baptist. We raised the kids Catholic with my wife’s Baptist influence. They all recieved the Sacraments. Our youngest had his second Baptism at Baptist church with our blessings and he and his wife are Evangelical Christians. “What a strange trip it’s been” ... ;-)
