I'm part of a small, private chapter fraternity and whenever I see stuff like this it never ceases to blow my mind. The pledging process is usually kept secret for the fact that if everyone knew what went on, there would be no spark of interest in it and it would kinda take away of the mystique of pledging itself.
With that being said, private events weren't even close to the same scale as this. It mostly consisted of legitimate team building shit followed by beer drinking and socializing... you know, stuff that actually builds a sense of brotherhood and community. Then, the next morning (which usually was either sat or sun), we'd wake up as a group and drag and our hungover asses to a food shelf or charity drive and put in community service to build our resumes, work experience, and P.R.
I know there are plenty of people who hate fraternities, and after seeing more and more leaks like this, I really can't blame people. I'm not going to deny that there are some fucked up organizations out there that do stuff like this, but in that, we take pride in being a testament that not all fraternities are the same.
As far as I see it, fraternities probably won't be around too much longer. There has been a clear drop in people pledging since incidents like this have come to light. In some cases, it might be for the better, but if my chapter is affected by this, it will be sad to see it dissolve.
