So a guy from the all black fraternity is lecturing us about the evils of a lack of diversity?
Conquerors often feel the necessity of lecturing the vanquished.
I was a frat-rat back in the early 70’s and, even then, traditionally White greek organizations, both male and female, had Black, Hispanic, and Asian members, among others. I noted the same thing during my graduate study and as an adjunct faculty member.
At the same time, I have never seen a non-Black member in any traditionally Black greek organization.
So who are the racists?
Tryal black historical colleges today. Some of the most racist people i ever met and lived with were from them.
