Coworker probs

How is everyone with their coworkers? Do you get along really well or are there some you just tolerate? I started a new job and so I am still getting used to everyone. But one of my coworkers knows I am a Christian and she keeps bringing up stuff about how she hates people who are like me who don't agree on some things that she does or likes. I have never voiced my opinion on anything or said she has done anything wrong. I just said I went to a Christian college and I go to church so I think she just assumes what I believe in. Anyways, she does not direct what she says at me but she says stuff about my school and the people there and how she hates what they stand for. She says she hates those type of people. And it offends me, because the school believes in everything I do. I am one of those people. I am such a timid, quiet person so I am not the type to say anything, I just let it slide but I am just such a people person and I want everyone to like me, it's unsettling for me to hear stuff like that from my coworker. I wonder if she secretly doesn't doesn't like me. Also, she is just out of high school, so she is very young.
