Responding to Mortensen’s Unauthorized Postscript

I don’t understand Mortensen’s style of communication. His main point seems to be a critique of the shallowness of contemporary worship, both in music and lyrics. This is something that needs to be addressed. However, his article reads less like a thoughtful critique and more like a condescending lecture. His explanations of meter, rhyme, and imagery were rather embarrassing. It was as if he assumed that none of his readers had taken a college literature class, so he had to articulate and demonstrate types of each before challenging us to make better use of them. He could have made his point more delicately and concisely by assuming a broader knowledge base for his audience (which I think is reasonable to expect). My question is this – can we talk about these sensitive issues with humility and respect while still communicating our desire for change?
