I’m a student here and I don’t find people closed minded.
Yes, there are some rules because the school is Jesuit but students generally figure out ways around them when they want. For example the health center doesn’t give out birth control (so go to the drug store down the street), there is a 3AM curfew for opposite sex guests (not an issue if you live in same dorm, otherwise ask a friend of your significant other’s sex to sign them in the dorm for you). etc.
If you want religion in your life it is readily available, if you don’t it is not pushed on you. Some come to Fordham because it is a great school and others do want the Jesuit aspect. In terms of day to day life, you will see priests, crucifixes, a nativity scene at Christmastime around campus but that’s about it. You should be respectful of religion if you come to Fordham and keep in mind that theology and philosophy course are part of the core curriculum.
