Duquesne University is a Catholic school in Pennsylvania.
So is DePaul University, just outside of Chicago. DePaul has a thriving Secular Student Alliance group — the DePaul Alliance for Free Thought — which encourages conversations about religion between religious and non-religious students. They also bring in speakers for the school, question long-held beliefs of everyone, and raise awareness about atheism-related issues for the school population. They’re less interested in “proselytizing atheism” and more interested in educating people about religion and getting them to think critically.
