The argument is simple:
1. Universities have a fiduciary duty to their students to hire competent instructors.
2. So far, most of the madjuncts’ criticisms of our paper have been so feeble or irrelevant that only people who A) lack basic reading comprehension skills, or B) lack basic reasoning skills, or C) are intellectually dishonest could have made them.
3. If someone exhibits A, B, or C, he is unlikely to be competent instructor.
4. Therefore, universities have a fiduciary duty to their students not to hire these madjuncts.
