You know, I've had people assume I was an inferior software developer solely because I was in a social fraternity and therefore must not have spent any time studying for my exams or working on my problem sets. That's not really a nice prior to have about an individual, sort of how it would be considered quite offensive to assume that a woman were an inferior software developer due to her gender.

Additionally, I'm not going to pretend that Greek life is 100% free of douchebaggery. Some people in fraternities do bad things to other people, or harbor bigoted worldviews. I feel that you grossly overestimate the proportion of people who do. To address the racial and sexual homogeneity point, I'm fairly confident that every single fraternity at my alma mater had individuals of color and homosexual individuals. My own certainly did.

I'd also like to point out the obvious blanket statements you've made about the demographics and attitudes of fraternity members. However, I really don't think anyone or anything can budge your opinion.
