Tribalism = the behaviour influenced by strong loyalty to a tribe.
Early on New Years Day 2013, two high-profile competitors from the Lloyd Irvin Brazilian Jiu-Jitsu team – Matthew Maldonado and Nicholas Shultz – raped a drunk teammate in a Washington D.C. parking lot. The assault was captured on video and hit the BJJ world like a firestorm. About a week later, another story resurfaced: a gang rape case from 1989 involving a Lloyd E. Irvin Jr. Things got ugly. A debate sprung up about whether a “rape culture” exists in Brazilian jiu-jitsu. Tribalism reared its (sometimes) nasty head in a localized exhibition of a species-wide phenomenon.
