Having said that, My wife and I have both had some wonderful experiences with Delta Sigma Theta sisters in our lives.
The long time principal of my son's elementary school who was a good friend to my wife and myself is a Delta sister. And yes she did have some Elephant decorations in her office. She was promoted a couple of years ago to being head of Title I programs in Montgomery County (The county due north of Washington DC). (The school system arm twisted her into interviewing for the job and then didn't interview anyone else.
The University that I attended (Carnegie-Mellon University (PA)) did not have a Delta Sigma Theta chapter (or for that matter any of the Noble 9). My wife's University (Frostburg State University (MD)) did and my wife said that she liked the DSTs better than she did the other Noble 9 Sorority that was there.
(And if you are wondering about skin color, my wife and I are about the same color as President Obama's mother.
