I don't have much use for the notion that hostility toward religion generally or Christianity in particular pervades American media. Yes, Bill Maher can be kind of horrible, but there's really just the one of him on TV.
In the early days of blogging, when it seemed like a mere handful of people were conversing on-line, I encountered Doug Hagler, Aric Clark, and Nick Larson (also known as Two Friars and a Fool). They were students at San Francisco Theological Seminary, and full of fiery passion. I loved reading their writings as they playfully and consistently challenged theology, culture, and the church.
