Gang rapes are so fascinating as a sociological phenomenon.

I can understand the motives for rape (sadism + low empathy + warped sexuality) but gang rapes are where my RS armchair sociology is at a lost. 

If there weren’t so much documented proof, I’d never believe that an entire gang could be formed for the express purpose of raping a woman in a front of a bunch of naked dudes that have already raped her. Unicorns seem more believable than this, yet there are countries where a whopping 14% of men admit to have engaged in gang rape before. 

Like what?? I don’t know what’s weirder—wanting to engage in a gang rape or finding enough like-minded dudes to do it with you. Ideally, I’d like a Paglia-esque explanation of this phenomenon, but I’ll settle for an evopsych one.
