This is a video of a man telling us how he feels about Muslim students getting mad over crosses in a Catholic school. It's ok for Muslims and all other religions to go to a Catholic school. If it has a good reputation or good academics, and it's a good fit for you, then go there and learn. If you're going to go there though, don't complain about some things that a CATHOLIC school does. At every private Catholic school, there is going to be a cross in every room, there is going to be a prayer before classes, and chances are there are going to be nuns walking the halls. If you have a problem with that then maybe a Catholic school isn't where you should be. I think it's wrong for the Muslims to complain about something like this, especially since they're the ones that wanted to go there. If you want to walk into a classroom and not see a cross, then go to a public university.
