Because the professors and students make Mormon jokes and are critical of the church. But then when the University of Utah's most visible employees compliment the church by highlighting famous alumni (Nelson, Maxwell, and Worthlin back in the day), they are just doing it to "rub it in" and criticize BYU somehow.

Geez. Persecution complex much? Regardless, there is no mention of BYU in his tweet so taking offense really speaks more about you all.
