If you're getting upset over being referred to as a "white girl" you should take a look in the mirror and stop being so retarded. Everyone refers to college aged "women" as girls. "Hey, let's have some girls over tonight." No one says "Let's invite over some fine young women tonight."
Secondly, I'm sure most of you were only involved in XC/Track in college so have no idea about fraternities/sororities/stepping. Every predominantly black fraternity/sorority starts stepping from the moment they get in. Stepping is a HUGE deal to them. They compete yearly on a school basis, as well as nationally. Obviously, a bunch of caucasian sorority women(good enough?) coming in and winning a competition like this is a big deal and noteworthy.
