Two Gods

In modern discussions, many have stated that the God of the Old Testament and the God New Testament as two totally different Gods. One being very cruel and the other being very good. Dr. Richard Dawkins states,

The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.

Is he right?

Are there two Gods?
