Deputy,
I will leave others to convince you that a theist can be atheistic towards other Gods not of his choosing. I fear you will get trapped in a logical quagmire before the debate is up!
However on this point:
I don't believe it's as "dark" as some would claim.
The use of the word 'claim' is interesting, as it does not speak the truth of the situation. You sentence should read in order to be consistent, 'I don't believe it's as dark as some would believe". Think about it.
So what do you do with Romans 1? Romans 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, 19 because that which is known about God is evident within them; for God made it evident to them. 20 For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.
Yes, what do we do with it.
1) We have a few choices. The first and most obvious one is to conclude that this is a statement of a religious mind, written in an unenlightened age, in a country full of religious fanatics, without the benefit of science to help the statement on its way by a person who truly believed that he was being used as a mouthpiece of some unseen being.
2) Another option is to take the words as true and conclude that God is a brutal and sociopathic liar. I state this against a backdrop of the fact that everything he 'designed' depended on the killing of other creatures, from microbe to blue whale in order to to survive. In order to facilitate such a Universal Killing Field, God introduces the idea of camouflage so that some are cunningly deceived into death, poisons so that some are brutally injected with toxic chemicals before being eaten, brute force so that some, like the Praying Mantis grabs its prey and eats it head-first, while it is alive. The thing this all has in common is a violence far removed from puffy clouds and gorgeous sunsets.
3) Conclude that in order for life to survive the process of evolution finds its own common level, unaffected by human emotion or Sky Gods and does what it must to ensure survival of the species, including our own.
I am sure that you wil have other options to add. ;)
