Students publicly Mocking the beliefs, history, practices of another group.
University Administrators, Coaches, Teachers allowing the mocking to exist year after year?
I’m don’t believe BYU students have publically mocked another group at an event - but I believe Mormons have been publically mocked multiple times at Stanford and Cal (and Utah). I’ve seen it.

Does BYU have policies and rules that impact others not following or Believing Mormon doctrine, yes. But they do not allow administrators, teachers or students to publicly mock others and their views/beleifs.

This poll didn’t define tolerance deep enough to get to a conclusion based on this poll’s results.
