Richard Dawkins and the God of the Old Testament

[Angrboda]

Wiker notes that in coming over to the atheist side, we face a number of new problems that arise.

First of all, as he himself admits in his book River out of Eden, in coming over to Dawkins' side, we have thereby embraced a cosmos indifferent to good or evil. As a consequence, we immediately face a dilemma: we have no moral grounds for condemning the actions of God (He doesn't exist) or the characters in the Bible (good and evil don't exist). Since God doesn't exist, there is no reason to work up a froth of indignation against Him, anymore than against the lunkheaded Zeus in Homer's Iliad.

Atheism doesn't equate to moral anti-realism. Your 'ethicist' has erected a moral straw man. Total fail.
