I think one of the issues Margaret points out though is that we use the same language to describe a variety of different experiences. In the US Campus study that found that 20% of college women were sexually assaulted that included everything from unwanted touching to rape, no differentiation. Now, unwanted touching is still unacceptable but no one's arguing it's the same as rape, but that's what happens often because of the language used. On a side note that study also had a 19% response rate which is problematic because people are more likely to respond if they've experienced sexual assault (it also found that 5% of men were sexually assaulted) so the results are questionable at best.
