I think this organization sounds like a good thing. The girls in it sound fairly western if they don't wear the head coverings. That's a good thing. Hopefully, two things will happen. First, they will 1) denounce horrific acts of terrorism done to Christians, Jews, and Islamic women in the name of Islam and 2) Realize their professed religion is not false and convert.
I think there is a real possibility of these things coming to pass. If they start making statements, even if only to each other, then devout Muslims on campus will begin to harass them.
