This is the kind hurt, anger, and bitterness that I sometimes see from some of my good friends here who ridicule those of use who are believers. 
That guy is a nut, almost as nutty as you.
We 'atheists' (a term I dislike) are usually not bitter; my only interaction with religious nuts like yourself is on internet boards so it's basically a non-issue. Arguing about the 'truth' of Genesis and Exodus is just good fun because they are so ridiculous and universally acknowledged in higher academia to be myths and stories.
