It is BS.

2014-2015 per semester tuition for undergraduate students who are LDS will be $2,500; non-LDS undergraduates will pay $5,000 per semester. LDS law school students will pay $5,810 per semester; non-LDS law school students will pay $11,620 per semester. It is a LDS university, after all.

Sounds like very reasonable tuitions in either case. Further, I have no problem with them charging more to non-LDS. They are a private university, after all, and probably view their own as having already paid some of their tuition in tithes and offerings much as a state university charges lower tuition for residents because (theoretically) they've paid for the difference in taxes.

In general, I've learned to take anything the more prominent bigots on this forum post with a large grain of salt.
