If the same kind of reasoning produces support for two different conclusions then the reasoning is delusional. By your host here, John W. Loftus ;-)--Example 1) Ontological arguments for God's existence equally support the Oriental conception of God, or a trickster god.
--Example 2) The same kind of arguments exonerating God from being evil also work in reverse to exonerate an evil God from being good.
--Example 3) Arguments deflecting the problem of divine hiddenness for the Christian God also work to deflect the problem of divine hiddenness for Zeus, Odin, Thor, Re, Hathor, Apollo, and Artemis.
--Example 4) Pascal's beneficial argument to support belief in the Christian God also works to support the evil Egyptian god Set (Seth), and the Greek gods Minos, Styx, Tartaros and Thanatos.
--Example 5) Arguments supporting the proper basically of belief in the Christian God also work to support the proper basically of belief in Allah. Somebody stop me!
