It seems to me that everyone thinks they pledge "harder" than someone else. Unless they are able to experience initiation through each organization, they will never know. I know that I did not "tip-toe" into AKA.

Also, I find that most neophytes seem to think everything they have experienced was "harder" than what someone else went through.
As far as these ladies offending you, are they really your friends? One of my best friends in college and I were on line at the same time, but she was pledging DST. With the exception of a joke here and there, we never said anything to offend each other because we both knew how much our sororities meant to us. She would say things like pink and green does not match and I would say be careful because elephants are afraid of mice. I mean, there were little silly jokes just between the two of us.
Before I became an AKA, I would take offense to things people said. However, my friends knew that I really wanted AKA with all my heart and respected my choice.
