It seems that the list of peeves in the OP could just as easily apply to American pop culture in general. Lack of originality is certainly not confined to evangelical Christian circles- just listen to any Top 40 radio station, visit a flea market, or watch another remake movie. There seems to be a mental indolence, insistance on instant gratification, and self-centeredness that is pervasive in America, not particular to Christians. The characterization of Christians as easily offended and uninterested in the here and now could as easily apply to every litigious, non-recycling, cigarette-butt tossing, gas-guzzling consumer out there.

Should Christians be lights to the world, conduits of God's grace? Absolutely! Do we often fall short? Of course! But as with most of society throughout history, one needs to take a look outside the main stream to see originality and excellence.
