I think that the problem still exist. But I think it relates to the schools, and not so much the organizations.
The year the incident at Georgia took place, there was only one african-american woman rushing. Out of 1000 PNMs.
I am not surprised that conversations ensued regarding that fact. And the sorority that did not invite her back was not the only one.
Several articles noted that she was unhappy and about to drop out of rush. Surely not because of one sorority. What happens at Georgia, happens other places I am sure. Why should a non-caucasian woman feel so uncomfortable going through the process?? I think these schools should work harder on ways to encourage diversity. If I were 1 out of 1000 I would have wanted to quit too!
