Having not even bothered read the above linked article, I doubt they are any more rapey than the others. Men, especially in groups, are pretty rapey.
From the "I like bleak books and I cannot lie" dept, I recently picked up
Missoula. Great book. Pretty damn bleak. Illuminating tho.
My takeaway from the book was that our (western, American) general understanding of trauma and truth tends to fuck over rape victims. Add a bit of intense tribalism (fraternities, sports teams, etc) and give the elders of that tribe some influence in the news, politics, or law, and the rape victims are basically fucked two or three more times on the way down.
