If a White person brought this idea up to another White person, the other White person would freak out and report them. If a White person brought this up to 9 other White people, at least one of them would.
Seriously, how do 9 people agree to commit a gang rape? This kind of conspiracy is only possible because of the morally backwards, intellectually stunted culture these people come from.
Clearly you haven't heard about what happened in Berlin at the end of WW2. http://www.bbc.com/news/magazine-32529679
Anyway, obviously this is terrible but rape victims are a severely misunderstood group of people. It's one of the most under reported crimes because of how humiliating it is, particularly because it usually happens among people you know very well and have to see over and over again each time you walk down the street or through a hallway at work or at school, reliving what happened each time. It makes sense that reporting would be higher for people you don't know, especially people that police and society at large might be more willing to take your side against. Because as you might have noticed, the burden to prove what happened is on the victim and a lot of times it's not easy to prove. That's not to say these incidents are excusable or that they don't need to be addressed, but seriously, spare me the cultured white people BS.
