2. Searching "fraternity privatization college" I actually came across a blogspot talking specifically about fraternities in a privatized college background (without the focus on minorities). Looking at this student's opinions will be useful for dissecting the topic since it has several layers of things needed to research.
4. I also realize that learning about black history is also something that may be important to focus on. An example is how "The Divine Nine" black Greek organizations may have not existed if univerisities were as privatized back then as they are today.
Another book I've looked at that may be important is https://books.google.com/books?id=oDuBvb3oT6wC&printsec=frontcover&dq=fraternity+universities+worth+it&hl=en&sa=X&ved=0ahUKEwjzp-PzwZDSAhVILZoKHQ7CAs8Q6AEILTAD#v=onepage&q=fraternity%20universities%20worth%20it&f=false " "fraternity gang rape: sex, brotherhood, and privilege on campus", which delves into rape culture.
6. So far I did not find any controversies yet since I've only delved into the surface level of searching each "background" and how they may interconnect with each other (minorities, Greek life, privatization)
