> We now live in the most peaceful time in human history.
I would say we live in the most widespread Uneasy Peace in human history. And unlike religious peace which had occasional conflicts, a break in the peace now would mean annihilation. Is general peace, risk of annihilation better than occasional petty wars without annihilation?
> And just to be clear, we're contrasting this time of unprecedented peace with entities that have killed in spasms of violence with no apparent public casus belli than "my book is better than your book and it told me to do so?"
I quoted The Washington Post's opinion, which is hardly the number most favorable to religious causes. Plus, older books had higher numbers than newer scholarship.

Let's not confuse Protestant fundamentalism motivated by political ends with religion in general.

So said the French Revolution. They did everything they could to break away from religion - they even invented a new calendar starting at year 0 because... anyway. Didn't go so well, there were a few smaller revolutions afterward to get to modern France.
