There are no beliefs that derive from rejection of god claims
I disagree. Depending on what god claim you are rejecting myriads of beliefs might arise in you related to such rejections. Decision making would be vastly different between those who've rejected god claims outright versus those who believe or at least haven't rejected the possibility when considering the consequential results of their decisions. We can very easily see that in human behavior today.
This is exactly analogous to avampirism or aleprechaunism. Each is also the rejection of an existential claim for lack of sufficient supporting evidence to believe those claims, and there are no other beliefs apart from things like not needing garlic to repel vampires and searching for lucky pots of gold that derive from that unbelief.
And yet there are people who keep garlic near and who search for gold supposedly hidden by leprechauns. Wouldn't you say that their behavior is directly derived from their beliefs?
Beliefs can arise just as easily from those who reject such things as those who don't.
Beliefs fill vacuums in human sentience. Where one belief is rejected another directly related belief consequently arises to fill the void.
it doesn't include my argument of the opportunity cost of being a Christian if Christianity is a false religion:
It doesn't have to if the how the question was framed only includes the proposition that either the Christian God exists or doesn't exist.
In light of how the question is framed let me ask for the sake of argument what opportunity costs might be incurred if Christianity is a false religion?
Irrelevant to a discussion of the beliefs that come from atheism or any harm that comes from atheism. Being an atheist doesn't make one want to kill, and being an Abrahamic monotheist doesn't prevent that desire in people.
This is a response to what I said which was...

How many have died at the hands of communist ideologies for instance?
Your response may be correct as stated above here but I'd say what I said is relevant as a representative example response to what you said previously concerning politicized religion versus atheistic humanism.
It Aint Necessarily So said:
They believe that organized, politicized religion is a net harm to society and should not be permitted to make laws.
You seem to be implying that the non religious are better suited to lead. The "They" being atheistic humanists as said prior.
And....
Many seem quite harmed by it, and the more zealously religious they are, the more the harm both to themselves and their neighbors.
This can hardly be demonstrated as being more quantitatively applicable to the religious than to those that aren't. Heck the two major wars currently occurring are neither religiously motivated nor being carried out in the name of religion. One might argue that the one is clearly motivated by secular ideologies.
Giving a reason is not promoting reason.
Interesting phrase. And what promotes reason? Being reasonable? And what is reasonable?
The reasons given are believed by faith, not derived from the application of reason to evidence.
Not all reasons given are by faith. Faith is supplemented by reason but reason is not or should not be unrealistically subjugated by faith. That is not what Peter was saying. Our reasons should be demonstrated through action, rational demonstration, eyewitness testimony, and record in light of what people actually experience in life. The last in other words....the faith addresses what actual people are actually experiencing...suffering, hopelessness, why their expectations and desires will always fall short of what is realistic in this current world, etc. Miracles and revelation aside it addresses why its good to behave one way versus another, why even though this world can offer no true justice there's still hope for such things to be realized. It promotes study of the scriptures, reigns and puts into perspective expectations of favorable treatment, experiences of miracles and wondrous signs and declares that faith must not contradict reality when the two intersect.
Christianity is a reasonable faith in my opinion.
