Why is Faith/Belief a Moral Issue?

[orangebox21]

People reject the Abrahamic deity because there is no evidence such a being exists and theists’ efforts to prove otherwise have not been compelling.

 
By what standard?

Why then is it considered a virtue to psych one’s self out and just believe in things one knows are not true? How is that good?  Why is it a moral failing to stand on one’s intellectual integrity?

Intellectual integrity as you have put it is limited in scope.  There are things we can know, things we might know, things we can know in the future, and things we will never know.  This premise isn't limited to the realm of religious faith.

Ascribing virtue or vice to one’s status as a believer makes as much sense as saying men who eat bananas are good in bed. Let’s look at the proof. Statistics show that men who are good in bed have at some point eaten at least one banana in their lives. So hands down, the proof is irrefutable. And when you consider the phallic shape of bananas, that’s even more proof.

I’m not trying to be funny. Just making a point about the ridiculous assumption that nonbelievers are essentially bad and believers are essentially good. Tell some people you’re an atheist and they automatically assume they know all about you and what you will do.

This is absurd.

It depends upon your definition of good.  Jesus said God alone is good.  If that is true then neither a believer nor an unbeliever is good.  The difference being that believers [having God living within them] can be good, yet it is not them which are good but Christ living within them.  If your defining good as 'gives money to charity' then yes some unbelievers are good while some believers are not.  Yet if a person gives money to charity but does so in order to get a tax break and praise from men [in other words out of a selfish motivation] can that be considered morally good?  What is your definition and standard for what is morally good?
