UF56,
I am so happy you talked to your Pi Chis about your concerns. I think that you should keep in mind that Jewish, Muslim and Buddhist women routinely join NPC orgs that were founded on "Christian Principles" and find homes and sisterhoods within these organizations. As for DPhiE, they seem to be a really strong house at UF and if you are feeling comfortable during rush that comfort will only increase if you do end up there and become friends and sisters with the actives and other new members.
At any rate, I think you are being really thoughtful about all of this, I am continually impressed with you UF women! I concur with the suggestion that you guys all take a photo together for those of us who have been hanging on your every post!
Good luck in your next round!
