Define "rape". Now figure out what definition those describing it in the article are using.
I've been in the army. There are rapes that occur. There are homosexual rapes that occur (both male and female). There are also a LOT of things that happen that get defined as "rape" that are downright debatable even when all of the details are known.
There are also a lot of situations where BOTH people involved are in the wrong, and further are the people who put them in that situation.
Furthermore, being practical, there is a rather substantial difference between approving of something, and recognizing that certain events are prone to happen.
