Thanks again for the context on MIT. The number in fraternities is to my view staggeringly high. According to this link:
apart from Wabash and DePauw in Indiana, MIT has the highest percentage in fraternities of any school outside of the former slave states of the South, and frankly rivals most of the schools there (less than W&L, but more than Ole Miss, for example).
My concern is frankly that I associate fraternities with a lot of things that are not progressive, such as this one from a person associated with an MIT frat →
I had perhaps assumed that MIT due to its scientific advancement would be socially progressive too, but now I am doubtful.
