I have more to add.
You stated that we should try to be the men and women that are organizations are trying to build.
Many people out there do not hold the ideals of their organizations as high as they should. Maybe they should...but they don't. But, at the same time, I think about the times I have made stupid mistakes and what was running through my head. That last thing on my mind was, "Man, if I do this, my organization would look down on me." Maybe this should be the first thing and it might be for you. But, it's not for me. The first thing that runs through my head is, "Would I be able to live with myself if I do this?" and "What would my parents think?" I respect myself and my parents more than anything in this world and no organization will come before these two things. I do love my sorority but the ideals were created by someone else. The only people's ideals and expectations of myself that I care about are mine and my parents. That is it. Is it wrong? Maybe.
I suspect that the these men who committed these rapes were not thinking, "What will my fraternity think of this?" I'm sure they were thinking of their own expectations for themselves which obviously were not very high. And, in a case like this, I don't think that any moral regulations of any organization can help someone who is as cruel and as mean to rape a woman.
There are all kinds of people out there. Crazy people are out there in the world. And, yes, some are part of our organizations. We bid the wrong people all the time. It's hard to get someone's life story from a five minute conversation. Most of us are hard workers who want to better ourselves. I just think that it's maybe only a handful of these crazy people who make greek life in general look awful. And it's these crazy people who seem to get their name and organization in the newspaper. Why must newspapers put someone's fraternity/sorority affiliation in the article. If someone was part of the math club on campus, do you think their organization would be reported in the paper if they committed rape? "John Smith...part of the math club...committed rape..." No way....it's boring and un-newsworthy. Now, a member of a fraternity committing rape...as angry as this makes me...the general public enjoys reading about it. Which brings me back to my point....if the rape was committed by an independent, it would never have been reported.
