SITH has generated various apologetic responses. Skousen claims Joseph and Oliver intentionally misled everyone by referring to the Urim and Thummim. Peterson's movie on the Witnesses portrays Joseph using SITH as a fact. Welch and his Book of Mormon Central "Kno-Whys" teach SITH as a feature, not a bug. Other apologists have used variations of these.
Dehlin has done numerous episodes based on the SITH narrative, claiming that SITH is one of the major causes of the faith crises he documents. Most of the CES Letter objections to the Book of Mormon depend on SITH.
