What should I do about my mother's proselytizing?

My mom is Catholic, and I'm a Pagan. She's known ever since I started practicing, and at first I didn't think she had a problem with it. Every once in a while though, she'll bring home tracts and Bibles and whatnot from church functions. She often has them out on a table I frequent by. At first I thought they were hers, but now I have found a tract in my bedroom. I suppose that all those tracts on the table were actually a subtle attempt to proselytize to me, and I'm extremely dense. Should I ignore it, or confront her? I'm rather upset by all this. After what I've learned about Christianity and the world, I would never choose to be a Christian.
