Rob Bowman, author of The Religious Researcher, has posted a rather tongue-in-cheek blog in which he reveals some common debate tactics that are used on both sides in arguments about religion generally when one party is losing the debate. As the introduction to the aptly named Twenty Ways to Answer Someone If You Have No Case notes:
Finding someone’s argument too tough to handle? Over your head in a matter of biblical exegesis, scientific evidence, or logical validity? Don’t despair. Now you can always respond to those smart-alecks and put them in their place. These are field-tested methods for diverting attention from the lack of substance in your argument. Never be stuck again for a snappy comeback!
He then identifies twenty common tactics, including The Amateur-Status Violation, The Evil Nun / Mad Scientist Defense, The Hoagland Hustle, The Moroni Maneuver and The Sextus Empiricus Switch.
