Religious Faith requires one to abandon truth, logic, reason, and honesty. It has been my personal experience that the God ideal and Religion are oppressive and abusive. These destroy trust. Without trust, you cannot have a proper, true relationship.
In order for me to have 'faith' in anything, a set of conditions has had to have already been established. One of these conditions is that truth is spoken, that accurate facts are given. Another is that oppression and abuse must be absent. Trust cannot be established if these conditions are not met. As soon as an intentional lie can be uncovered, or abusiveness is present, trust is lost.
God and Religion are unable to establish truth and accurate facts. They are abuse wrapped in a smiling veneer. Trust can never be achieved when these are present which means a relationship is never going to last unless one consciously decides to accept lies as truth, to become intellectually dishonest. At some point, reality contradicts belief/faith. This is the moment where a person chooses an honest or dishonest path.
For me faith did not stand up to truth and I abandoned mythology for reality. Once I did that, my nightmares stopped.
