The New Athiests have made a lot of noise in the United States. Their books are bestsellers, as are the replies (see Keller's Reason for God). These teachers who offer no hope for the world and no foundation to build a worldview are popular - in the US.
A friend of mine overseas was sharing that a well-meaning American pastor had come and was teaching apologetics when he started referencing Sam Harris and Christopher Hitches. He explained their arguments and then proceeded to teach how a Christian should respond. The content was excellent.
Only one problem - no one knew who these guys were or even considered Atheism to be a worldview. Now, according to my friend, the churches have a new problem - Athiesm. Why? Because the pastor from the US introduced a totally foreign worldview and had the exact opposite impact he wanted to have.
