In recent discussions with sincere nontheists, I have observed an underlying trend in nearly every conversation.
This trend involves the nontheist asserting for sundry reasons which they provide, that theism, specifically of the Christian stripe, is immoral.
Now, it must be stated that in general, this argument is not to prove in a direct manner that nontheism is true or that theism is false, but rather in a manner of sorts to convince the theist, specifically the Christian, that the Abrahmaic God is immoral. If God can be shown to be immoral, then it logically follows that the Christian God is not God at all, for the Christian maintains that God is omnibenevolent or all good.
The reasoning is simply that if God can be shown to be immoral from passages taken from the Holy Bible i.e. the appeal to the the doctrine of eternal punishment, and or by appealing to instances where people associated with the Church have committed immoral acts, then believing in Him and worshiping Him and propagating the gospel is also immoral and therefore the Christian is guilty of immoral acts based upon their adherence to the Christian Faith.
These arguments, according to the nontheist, justifies one in not believing that the Abrahmaic God is God at all, but merely an invention of men's minds. In other words, these arguments are used in an attempt to make a case that the position of one who maintains that this Abrahmaic God is God, and that He has revealed Himself through The Holy Bible is a position that is baseless, inconsistent, internally contradictory, and at best discrepant.
