FTS,
Ms. Mirazon appears to be - or have been - in the 'anthropologists of peace" camp where they believe hunter/gatherers were noble and egalitarian. This camp seems to have had its genesis from the 18th-century philosopher Jean-Jacques Rousseau, who believed Native Americans and other pre-state people as peaceful "noble savages". This camp is driven to ignore the facts and cloud the issue by using words such as war and massacre; they romanticize the hunter/gatherers as being more pure and ethical and it was only the white male farmer dudes who started ruining everything by planting corn, drawing imaginary lines around their farms and states, and waging war - or something to that effect.
Many scientists believe this is a politically correct view not based on actual evidence. Pinker states that this camp ignores the cumulative causalities of battles (not insignificant), the murderous raiding that some stateless human societies engage in, killing of non-combatants, and the other violent activities. Pinker states that the "quantitative body counts—such as the proportion of prehistoric skeletons with ax marks and embedded arrowheads or the proportion of men in a contemporary foraging tribe who die at the hands of other men—suggest that pre-state societies were far more violent than our own."
According to Pinker, the 17th-century philosopher Thomas Hobbes "got it right" when he called pre-state life a "war of all against all."
