Are male doctors studying to be proctologists forced to under go prostate examinations? I can't find any evidence that they are. As for finding it so unthinkable that a teacher would pull a bait-and-switch like that (because no one has ever had a teacher or business try that before) is rather odd since it's fairly common (maybe not at the academic level but it wouldn't be the first time a teacher has said something was optional at the beginning of a semester to later imply that while it was optional your grade will suffer if you don't do it).
The part that really gets me is how many are skeptical that it would have taken this long for someone to finally call them out on it is confusing. How many examples have we had of shady practices at a campus, university, charity or business finally being revealed after quite a few years because someone finally exposed the practice? How is it so far fetched to think that the same thing could have happened here?

There's just one article talking about the staggering amount of sexual abuse that occurs in our nations school systems. Hell, how long did it take for the Catholic church to finally be called out on it's handling of priests sexually abusing kids? Why is it so hard to believe that at a school a students have been for years told that having an invasive procedure performed on them is optionally only to later be told it was mandatory or their grades would suffer would take this long to come to light?
