They will get into it with you...... but civil they remain! 

I've had some really nice chats with priests and with some ministers (pastors or whatever they are called).  The ones that are, for lack of a better word for it, mature in their faith are the most fun of all because they don't feel threatened by the existence of an atheist in their midst..... heak, I think they might even relish the opportunity to talk to one.

That isn't universal, but it applies more often than not.  Even the ones that are more threatened remain civil.  Premies are the only religious people who have told me to f*** off.  I mean it.... the only ones, ever!  That certainly puts them in a unique group and I don't think it is one that they would really want to be associated with.  But hey..... at least they are in a  group, right?
