Hmmm... when I was a young co-ed, back before electricity and females were even considered "educable," four of the girls on my hall of about 75 were raped our freshman year, walking back from the library. There was no ROTC on campus so one can probably assume it was not some rowdy military-types who were the perpetrators.
Were there kids who cheated? Duh - of course. They even cheated in my high school where we had 13 students in a class (yes, 13). Were there gay marriages? Duh - no. Were there gays? Duh- yes.
Were there kids on campus who drank and smoked pot, even in their dorm rooms, even though it was a "You are expelled" offense? Of course.
None of these is a reason to choose, or not choose, a college, or a path forward for your future. People are sinners and therefore, sin, and it happens all over the world, in every institution.
I think the Service Academies do a better job of keeping cadets/mids safe than say, local community college, but that's based on anecdotal evidence and probably my own biases.
