Are all atheists this ill-informed about religion?

[Thumpalumpacus]

It doesn't really matter what sophism Delicate or any other theist can cobble together in defense of their omnipotent, omnibenevolent monarch. Such a creature is simply incompatible with observation of the world.
1. If God exists, there would be no unnecessary and excessive suffering in the world.
2. There is unnecessary and excessive in the world.
3. God does not exist.

If both premises are true, the conclusion must follow. The logical deduction of God's attributes guarantees the first premise, and the only justifiable inference one is entitled to make - given the information we possess - obliges one to grant premise two. Therefore, the nonexistence of such a deity is established.

I would disagree with premise one.  Scripture says early on, that this is not the case, and the suffering is the result of the fall and sin (separation from God).  Excessive is somewhat of a subjective and ambiguous term; but even granting this, I'm assuming that you are overly focusing on one particular attribute of God, apart from the others.  I don't think it is a contradiction in regards to God's attributes, that He allows suffering. 

I also do not think that you can enter into the Christian worldview just enough to critique and then back out before the answers.  Much of our suffering is self-inflicted (with the fall you might say all of it is). The suffering that you do see is temporary.  However, there is an answer to this, that the separation and suffering do not to become everlasting.   I don't think that your problem is with unnecessary suffering, just that you want it immediately.  Many choose unnecessary suffering over God.

Horseshit. I'd suggest you google the following terms before continuing this conversation: smallpox, tsunami, leukemia, mine collapse, sudden infant death syndrome.

Classic case of blaming the victim. When your wife gets cancer, don't you dare come here looking for sympathy. I will throw these callous, hateful words of yours right back in your face.
