What's Worse, Bad Apologetics or No Apologetics?

The golden era of Mormon apologetics ran from Nibley to FAIR and Old FARMS. With so many distinctive doctrines as well as a high public profile, Mormonism attracts a lot of criticism, so the urge to publicly defend Mormon beliefs is understandable, and there is now plenty of Mormon apologetics out there. What is badly needed is some reflection on the whole enterprise, trying to distinguish between good and bad apologetics and perhaps some thoughts on when the best response is no apologetics (polygamy comes to mind — trying to defend it just seems to dig a deeper hole). Enter the latest publication from Greg Kofford Books: Perspectives on Mormon Theology: Apologetics, a collection of essays covering a broad spectrum of views on the topic. We will have two reviews of the book and maybe a Q&A here at T&S in a couple of weeks. For now, I want to address a narrower question: What's worse, bad apologetics or no apologetics? Does bad apologetics do more harm than good?
