That great menacing Easter Island face.

An entire generation now regards Nirvana as its version of the Beatles. They are of course hopelessly mistaken, but I would not recommend you tell them so.

...it was not simply a matter of musical taste; whether you preferred the Beatles or [the Rolling] Stones said much about your personality and character. People who were happy, intelligent, well-adjusted, popular, clean, decent and punctual tended to be Beatles fans. Those who were evil, cretinous, scabby, drug-ridden, filthy, criminal perverts liked the Stones.
As for your author, I personally take no side in the controversy, remaining strictly neutral.

I was particularly impressed by the varying degrees of weathering and erosion seen on the different moai, which could be telltale signs of major discrepancies in their ages. The levels of sedimentation around certain moai also impressed me. Some moai have been buried in up to an estimated six meters of sediment, or more, such that even though they are standing erect, only their chins and heads are above the current ground level. Such high levels of sedimentation could occur quickly, for instance if there were catastrophic landslides, mudflows, or possibly tsunamis washing over the island, but I could not find any such evidence (and landslides or tsunamis would tend to shift and knock over the tall statues). Rather, to my eye, the sedimentation around certain moai suggests a much more extreme antiquity than most conventional archaeologists and historians believe to be the case--or believe to be possible.

'Rapa Nui' is about the conflict in the 1600s on Easter Island. It's about the clash of the royal clan and the working class.

The same solution--that Easter Island was once part of a much larger landmass--would also explain another, very different puzzle, namely the so-called Rongo Rongo script. It is unprecedented in human history for a sophisticated fully developed writing system to be invented and put into use by a small, isolated island community. Yet Easter Island does have its own script, examples of which, mostly incised on wooden boards, copies of copies of copies of much older lost originals, were collected in the nineteenth century and have found their way into a number of museums around the world. None remain on Easter Island itself and even in the period when they were collected no native Easter Islanders were able to read them.
