It does concern you, if you would like to learn. Growing up in a very non-Jewish area, I always invited others to ask me about my faith. It gives me the opportunity to share about the subject I love most and also the chance to learn something if they are asking me a question that I need to research.
Most topics regarding Christianity don't technically "concern" me, but I enjoy learning and understanding why other people think the way they do. I guess I just enjoy learning!!
So please, don't hesitate to ask questions and learn about Judaism. I'm more than happy to try and help.
