Tony Letford, I just came across this, which speaks to both what you've been saying and what I've been saying.

"Violence can take many forms, and since these forms can have different proximate causes, it is important to sort them out. Keeley (1996), for example, classifies Australia Aboriginal society as warlike egalitarian foragers, but Fry (2006) demonstrates that most of this fighting was rare, and usually fell under the category of feuding or revenge killings rather than warfare."

So perhaps our initial disagreement was one more of semantics than substance? My premise is about frequent, routine, non-personal, coordinated attacks on other settlements or groups for the purposes of securing some advantage, not personal retaliation based in passions or retribution.
