In defense of the OP, I suspect that honest-to-goodness deep love would inspire courage, hope, faith, and anything else that Malvora and Skavis would hate. It may not instantly cause them to be burned like a Raith but, since we know the White Court like weak prey, I bet it would cause them to not target people in a solid relationship. Maybe it's just my sappy side talking but I like to believe that real love inspires courage and hope.
