Shockingly, I'm not an expert on gang rape so I can't definitively speak on the predominant motive behind them. I would think that they are generally just the result of a bunch of criminal minded predators ending up horny and alone while perpetuating their own deviant thoughts. I could be wrong, but it doesn't seem like the type of activity you would do solely to strengthen a kinship.
That said, if there was a ever a group that was going to be inspired to commit outnumbered sexual assaults on women in the spirit of brotherhood and unity then that group would likely have a Baylor football scholarship in common. If there's a program that would steer clear of paintball trips and fireside chats in lieu of calculated acts of violence that required inducing young, vulnerable women with debilitating drugs then that program would reside in Waco, Texas.
It's almost like Art Briles heard someone use the term "rape culture" while walking past him down the street and he immediately decided it sounded like a hell of a team building philosophy without even giving it so much as a Google search. With 52 acts of sexual misconduct officially in writing, I am not sure anything would surprise me anymore. You could tell me that Art Briles sat at the foot of the bed using a significantly different type of rape whistle to make sure all of his players got their "reps" in and I would only think slightly less of him, because you can't really get much lower than scum of the Earth. To team up on 18-19 year old girls and come away afterwards feeling closer as a unit would be such a nauseating display of groupthink that it would make the gluten-free craze look like a product of individualism by comparison. Yet somehow - given the obscene circumstances - it feels like the most logical explanation for a football team turning a college campus into the type of environment that Liam Neeson would kill an entire roster to save his daughter from.
