Brown Paper Bag Rule

Back in the early 1900s, the first black sorority, Alpha Kappa Alpha Inc., had a rule that if a potential candidate was darker than a brown paper bag, she would not be considered for the sorority. About a year ago, I overheard a member of this sorority make a statement about another member. She stated, "She was surprised she was able to get in, being she was EXTREMELY dark." I was taken back, but made no comment because the girl who made the statement is a close friend of the family. I pose the question, does this underlying inside racism still exist in the world of sororities and fraternities?
