"Grief and a Headhunter's Rage"

This was a strange piece that i really disliked in the beginning but grew to enjoy and sympathize with the further in i got, and eventually i came to agree with what the author had to say on somethings although it still left me with a few questions.
I was frustrated in the first few pages on how he kept telling us how long it took him to understand the "significance ", the "power", and "force" of their words, and yet he it took him forever to get to why he couldn't understand what was going on with the damn words. I was screaming (in my head of course)
"Come On!!! Don't keep saying that! Effing tell us HOW you finally understood the power of their words, because if you don't understand, how the hell am I to understand, because the more you say that, the more empty your stupid words become to me. Rage from Grief?I've felt rage in depressed moments, but it's rage at how long it's taking me to pull myself out of depression."
He finally gets his act together and dives into the meat of things when he relates to us the tragic death of his younger brother and what he witnessed vicariously through his parents' eyes as well as what he himself was going through.
Shortly after this, his wife Michelle falls off a cliff, in a freak accident, resulting in her death. It wasn't until after these events take place that a he could feel the rage the Ilongots talk about amidst his grief and it finally dawns on him basically what everything is all about. He can start to see the silliness of himself as a traditional anthropologist, and the silliness of following the outdated methods in that profession. He sees the world as not arranging itself to universals as is commonly accepted in western culture, but is much more relative and subjective than that, and you know what, that is what is what actually makes sense. Every person and culture are slightly different, and what are universals but arbitrary titles given to accepted customs of a dominant culture.
He provides the audience with a great critique of other anthropological works (i.e. deep play), realizing that they are too detached and unemotional, hoping to observe life as if they weren't apart of it. A child studying ants, not interested in their lives, but them as a culture. He accuses traditional anthropologists with being overly rational and simplistic in their approaches to heavy subjects like love and death. He also critiques something called "cultural depth" which is the act of giving something more significance than it possesses in reality, just because it looks good, and adds so called validity for actions. it's a way of excusing undesired behaviour, blaming it on ritual or culture, when it is really something else all together, and maybe, what's really embarrassing or undesirable is the idea that everything has to be excused. Maybe it should just be, and those who do it should not have to feel like they need to explain for doing it, whatever it may be.
