David, Native Americans themselves do not agree as to how they wish to be referred to. Some object to being called "Indian" because it misidentifies them (and indicates that Columbus and many who came after him didn't have a clue as to where they really were and assumed that they [the "Indians"] were inhabitants of the Indian subcontinent or of what we now refer to as "the East Indies"). Some dislike "Amerindian" or "Amerind" because it merely takes "American" as an adjective and the original misidentification and turns them into a compound word.

On the other hand, some Native Americans don't mind it because it is brief, contrary to some of the convoluted attempts to be "politically correct."   For example, Native American author and poet Sherman Alexie says that he does not mind being called an "Indian."

By the way, you will note, if you scroll down in the link above, the number of novels and books of poetry by Sherman Alexie that have been published—not just on a web site, or self-published, but by big name publishers. Note also the many awards he has received for his literary efforts. At least one of his novels has been made into a movie.

And, also by the way, he doesn't go around in buckskins and feathers. He usually wears casual western dress and frequently wears a suit and necktie.

Sometime in the mid 1980s, I met a Native American writer (unfortunately, I do not remember his name, but he has several science fiction novels to his credit) at a Norwescon, a local science fiction convention (he, too, was wearing a suit, not feathers and buckskins). In a workshop in which we participated (on building a believable alien culture inhabiting another planet), he had a great deal to add to the discussion. One of the points he made which is most germane to this discussion is the following. Heed this, David, because it is important, relevant to your suggestion that Americans should do "Amerindian chanting and drumming."

He said that such things as chanting, drumming, and flute playing are more often that not ceremonies of one sort or another, generally of a religious nature, and they should not be performed out of the context of the ceremony. For this reason, they do not like it when anthropologists or ethnomusicologists try to record their music. To "perform" these chants by playing recordings of them, or for non-Native Americans to try to perform them, in essence, is to violate their equivalent of one of the Ten Commandments: "Thou shalt not take the name of the Lord Thy God (the Spirits) in vain." They feel that for non-Native Americans to sing these chants verges on desecration.

So—out of respect for the culture(s) of the Native American peoples, your suggestion that Americans should do "Amerindian chanting and drumming" displays your lack of knowledge.

And lack of knowledge has been your problem all along. You know not whereof you speak. You should be trying to learn. Not telling others what they should or should not be doing.
