The role of religious affiliation in the United States is changing.

According to a recent survey from the Pew Forum, one in five Americans is not affiliated with any religion

A small part of this growing group is made up of atheists.

Last weekend, hundreds of atheists gathered in the Bible Belt – Springfield, to be exact – for Skepticon, a national skeptics convention. Not all skeptics are atheists, but many of them are.
