You're so enamored of BYU's position and status as a safe place...even the safest place...that you fail to see what is in plain sight. Sexual assault happens at BYU...much more often than you'd believe. You believe that it has to be substantially lower than elsewhere beacause of the honor code and LDS population.
Nope.
LDS culture doesn't keep divorce rate down within the church, and it doesn't keep Utah from being the online porn capital of the USA and ground zero for affinity fraud.
