There can't possibly be any bias whatsoever among the staff because of your scintillating evidence.
While I do think that having an active Mormon owner might passively lead to a toning down of the more incendiary swipes at the church, this bias is rooted in decades of church opposition. Its entire historical purpose is to act as a counter to the predominant culture/religion.
You must be really young if you're not familiar with the history and ignorant about the secular journalist psyche and how it despises conservative and religious orthodoxy.
