You'll find people recoil from Atheists more often than you would think. It's good to be outspoken, but you'll learn to grow a thick skin and how to defuse fundamentalist explosions. My advice is ask questions, the beliefs that propagate religion are fascinating insights into how people work, try and use the conversion attempt to learn more for your own sake, and maybe get them to ask questions of themselves they might not have normally.
My religion is the understanding of my world. My god is the energy that underlies it all. My worship is my constant endeavor to unravel the mysteries of my religion.
