Great analogy! I felt that way watching this. They were essentially saying that if you questioned their "truth" in any way you are not ignorant - you are willingly evil. What an interesting argument technique!
ARGUMENTUM AD HOMINEM
Description: An argument that attempts to disprove the truth of what is asserted by attacking the speaker rather than the speaker's argument. Another way of putting it: Fallacy where you attack someone's character instead of dealing with salient issues. There are two basic types of ad hominem arguments: (1) abusive, and (2) circumstantial.
