I know what you mean! It happens with locals too - when I joined my local, I got a few snide remarks about how my sorority was for women who couldn't get into the "real" sororities.
Never mind that I was the only woman in my pledge class who had even gone through FR. (I dropped out.)
Even our Director of Greek Life bashed us! He was giving a presentation and said "There are four sororities at this school." The then-president of my sorority was there in the front row, and she cleared her throat loudly. He looked at her and said, "...oh, and you guys" and then went right on talking without correcting his previous statement! He was doubly wrong, because he didn't count Alpha Kappa Alpha either.
