Of course the easiest response to make is that because he is a Muslim he is obviously a liar.
Again, I specifically said I won't factor that in as it is so obviously flawed without that, although a work of Islamic apologetics is not necessarily the most trustworthy.
When such a work uses very strange methods to make a very "convenient" argument, we might start to wonder even more.
I'm more than happy just to focus on the methods used though.
The addressed this in the book along with the methodology they used to deal with this.
It just says "the numbers are inaccurate but we will use them anyway"
How do you think people got casualty numbers in the 3rd C for example? What methodology did they use?
They largely made them up.
Do you, for example, think Darius invaded Greece with 2.5 to 4 million troops as the sources say, or that these numbers were just made up to mean "a very large army" (the real number would likely have been 3-10% or that)
If Army sizes are ludicrously overstated, why should we assume casualty figures which are exponentially harder to estimate were more accurate?
And if numbers may be out by a factor of 10 or more, what value do they have?
Which wasn't done. They only included wars in which there were more than ten thousand caualties.
A somewhat pointless quibble, that avoids the main point. Small wars make no real difference to the number.
The point was that using the idea that any war that happens in a "Christian" part of the world as being is inane.
For example, counting WW1 and 2 as "Christian" Wars is stupid.
Counting cholera and smallpox related deaths in the Americas as "Christian" is stupid. As it comes from the subcontinent, obviously Cholera should be considered a Hindu disease
Not relevant here as the deaths were purposefully isolated to violence causes.
No they weren't. Are you saying Europeans physically killed 16 million Native Americans.
Almost all pre-modern casualty figures are primarily due to disease and famine (yet no one adds Spanish Flu to the WW1 death toll). And when you lump together several decades or even centuries of intermittent conflict into one "event" and count every death in that period as being "violent" you end up with pretty meaningless stats, even if you assume they weren't simply made up (which they mostly were).
We are comparing the causal violent deaths of one cultural identity to another. Nothing more nothing less. Of course it might be more interesting to show the deaths as a percentage of the population of the earth at the time but I haven't come across such a study.
We are comparing apples to oranges, while also including pears as apples and melons as oranges and doing the comparison using only our ears.
We are comparing mostly made up figures, for pretty nonsensical cultural categories, that may or may not be violent deaths and depend significantly on the longevity of cultures, their record keeping, population sizes, technological advancement, geography, resources, climate, epidemiology and many other things and saying these deaths should be attributed to a single cause - religion - and that we can make a meaningful comparison based on this.
People have countless cultural identities.
Mongols conquered Islamic countries then some converted to Islam and continued to be violent and warlike. Instead of looking at Mongol culture, we arbitrarily say the original conquests were "motivated by paganism" and the latter "motivated by Islam"?
Sure there could have come to exist other reasons for causal violence, but that didn't happen. Of course you can throw up counter-factual speculation but all we actually have is what did happen and the numeric consequences.
You threw up a counterfactual by saying "how many more people would be alive?"
The answer is we don't know but there is no reason to assume it would be more.
I don't agree that humans are violent by nature. Humans are motivated to violence by their human leadership instilling some claimed "just" causality in the populace. Humans can live peacefully if their leadership would allow it.
Science and all of human history seem to suggest otherwise.
Seeing violence as a kind of "error" that can be fixed is just magical thinking of the purest kind.
Prone perhaps that humans can be motivated to violence but the motivation has to be there. I don't agree that the majority of human if left alone will resort to violence.
Humans aren't left alone, they form groups, they struggle for status within these groups and these groups come into conflict with each other over resources, access to mates, an easier life, etc.
Like all animals, humans are in competition with humans and other animals.
