All of this talk of a sister not being accepted because of her religion surprises me. Not once has a sister's religion come in the way of daily activities. Our chapter is pretty reflective of its larger surroundings; not many people are observant in their religion, and it really hasn't impacted how she's treated in the house. The only time it became a problem was when our Catholic president did not want us to do anything with the on-campus women's center (which does a lot with domestic violence awareness--one of our altriusms) because they were a pro-choice leaning center. That could happen with anyone, really.
And since when is an atheist a pagan?
