LUHE,
I have an immediate and passionate response to anyone who uses loaded language in order to control the evidence, the argument and people. Geesh, I wonder where that came from?
Trying to control the argument, the facts and people by manipulating the evidence around words such as 'war' and 'massacre' is symptomatic of what cults do (oh, THAT"S where I got it). Rousseau's views were not much more than a philosophy driven by White Euro Guilt. There wasn't evidence in the 1700s to really support it. The WEG lives on. Pinker cuts through the BS (Imagine why I would like that) and makes it clear that state sponsored warfare obviously wasn't around before states were invented, but it was a lot more dangerous being human before states came into existence.
State sponsored war occurs far too often and is bloody beyond comprehension, but the day to day existence of those within the state is such that few of us will ever be faced with a life or death struggle, much less on a day to day basis, just to survive.
Pinker rightly pointed out the mountains of evidence (skulls, bones with knife/axe wounds) that show up in a very disproportionate manner within the hunter gatherer fossil record. To 'ignore' that evidence because it doesn't nicely fit into preconceived and misguided ideals built on political correctness and guilt and routinely managed and massaged by predetermined, loaded, words and skewed results isn't science.
