I'm an atheist - should I go talk with the priest at the local church?

I feel like I need to have actual conversations with theists to become more articulate when explaining my disbelief in God. I don't feel the internet is good enough. It's important to me because I have a need to be sharp in my opinions. Where can I go to talk to theists willing to have discussions with me? I'm not sure how a priest or other religious clerics would react to an atheist. Will he kick me out or what?
