I don’t see why it should be “us vs. them” in terms of daily life and what we participate in. Things involving large groups of people like a university or what makes the news (or which stores are successful in an area or which politicians are elected and which policies come to be law, etc.) help to form what our society is, and if we’re just sitting out and not taking part, I don’t think we can complain when things don’t align with our beliefs.
As others said, I think putting yourself in these situations and being an active member of society will do good by showing others a positive example and also by exposing you to the opinions of others - which hopefully will lead you to be more empathetic towards those that are different (I feel this was the case for me personally) as well as possibly offering challenges to your faith, which should make you question certain areas and make you think and pray and research and become better at defending your faith and deeper in your faith (again, speaking from experience personal here.)
I am still not the most competent at explaining or defending the faith, as I would like to be, but having the chance to have discussions with friends from different backgrounds and faiths has helped me.
Good luck in whichever path you decide on!
