According to a recent study of 27 schools, about one-quarter of female undergraduates said they had experienced nonconsensual sex or touching since entering college
So basically they asked about touching and sex just so they can put the phrase "nonconsensual sex" and "one-quarter" together?
Those 2 are nowhere near the same level of severity to be reported in that fashion.
I've been touched plenty times nonconsensually, I figured "that's a bit too familiar" (yes I'm a man, yes by women), however I wouldn't place those occurrences nowhere near anything having to do with rape.
The most difficult thing in the world is to know how to do a thing and to watch someone else doing it wrong, without commenting. -- T.H. White
