What Major Intellectual Issue Most Keeps You From Accepting The Christian Narrative?

[downbeatplumb]

Atheists are not responsible for the most atrocities. 

The holocaust was catholics.(In the US it looks like the protestants want to start up round 2)
The holy wars of the early modern era catholic V protestant
Crusades Catholic V muslim.
The massacre of the cathars, slaughter of "witches" all religiously motivated.
The murder of the maya and Aztecs killing hundreds of millions catholics V whatever the native population believed.
etc etc etc.

Centuries of Christian killing, stamping out all who questioned their faith.

Did you ever wonder why Christians are "god fearing"?

I notice in order to make your point you literally have to span close to 1000 years, meanwhile Communist regimes are responsible for 149 million deaths in less than 80 years.

Yes Christianity has been shitty for well over 1000 years.
The deaths in the name of communism, you will notice, are not deaths in the name of atheism. 
And I have long said that people will commit atrocities in the name of any strong idea.
People will, for example, shoot up a pizza place because they have been lied to about paedophile rings, they will kill themselves for womens suffrage and they will kill for communism. But mostly they kill for religion, or has 9/11 taught you nothing.
