Well, atheists can't hate God. How to fish on their own can not fly into space. Because in the atheistic worldview there is no God, simply no. Therefore, any feelings to non-existent too. So the question is fundamentally wrong.
Well, of course atheists hate God. Here's why.
Classic "Atheists hate god" fallacious arguments....

@BADecker
Why do you hate Allah so much?
Why do you hate Ameretat so much?
Why do you hate Xuan Wu so much?
Why do you hate Zeus so much?
Why so much hate towards these gods?
My hate of false gods is not a passion filled hate. Why hate them? They are causing people to be destroyed.

Interesting. Let's look where we're at:
1) You've placed yourself above god, thus making yourself a false god.
Check2) You say you hate false gods.
Check3) You say false gods are causing people to be destroyed.
CheckTherefore...
By your logic, you must hate yourself for destroying people.

Oh dear.. The devil has you well under his wing.
