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

[Shell B]

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.

He didn't, though. The first thing he mentioned was the Holocaust, which happened at roughly the same time as Holodomor and other Communist-led genocides. I think we can all agree that people are killing people, but there's never been an atheist regime that was like, "Kill everyone who believes in god."
