Skimming through the article, I find the Nacirema to be a very strange people. They believe the human body to be ugly and to have diseases and disabilities if certain rituals are not followed. They follow secretive rituals every morning to rid the body of disease and even have special medicines prepared for each and every disease or disability that could happen. They even go to the extent of visiting a holy-mouth-man who will open holes in the Nacirema's teeth and fill them with paste believed to rid the mouth of disease. The medicine men of the Nacirema have a latipso where the sickest patients are treated. The patients are made to go through torment while they are being "treated," getting poked and prodded, having magic needles stuck into them, and being forced to eat substances that "heal" the subject. Many patients do not make it out of the latipso alive, but the Nacirema have faith in the medicine men. The Nacirema also go to "listeners," who listen to all of the patient's troubles and fears and somehow remove the devils in the minds that makes the Nacirema think bad thoughts. They have feasts and fasts to fatten and thin people, and procedures to alter the body shape if it is undesirable.
I have heard of very many strange people, but these are the strangest. Following rituals to extinguish disease? Drilling holes in teeth and filling them with magical paste? Making sick patients go through torturous procedures and having a strong chance of not being cured?
I suspect some kind of strange gene that all Nacirema people have that makes them think like that.
But then again, if aliens were to land on Earth and look at us, then they would probably think we were the weirdest people they had ever encountered. We even think many of our own kind strange - people who have fetishes, people who do or don't like a certain object, people who do strange things, often dangerous, etc.
The Nacirema may be strange people, but I think that the article is unjust in that it judges them as crazy people who may have mental issues.
They're Americans.
