I'd like to leave a few comments about this topic
I'm a strong atheist, and so far time has only increased my stance. I'm not one of the full anti-religious atheists, I'm open to evidence that disproves my beliefs. But let's avoid the messy topic of whether a god exists, or which one does exist, it's an aggressive topic and I don't want to go through it.
I've based my opinion off years of studies and reasoning which have revealed many holes in Christian belief and contradictions with established fact that leave me unable to interpret the Christian belief as fact.
The problem is "righteousness" is entirely objective. While I hate to invoke Godwin's law this quickly, even Hitler believed himself right. So asking if its right would become whether you believe it's right, making the question redundant.
