What is immoral is choosing a demonstrably poorer information set upon which to make choices. Faith allows any behaviour and argues that it is moral because of unverifiable reasons. Faith allows you to burn people , practice genocide, assume control over people's relationships, extort financial support, subvert legal systems, break up families , go to war / not go to war regardless of moral consideration. Faith is the ultimate excuse for behaviour.
No moral behaviour I exhibited as a Mormon was based upon sound logic and a good deal of immoral behaviour was unwittingly condoned. Nothing moral was exclusive to my faith.
Moral behaviour I do now is the result of deliberation and weighing up alternatives. I am responsible for my behaviour in a way that faith never let me be.
