My question is: Is Satanism an "american religion"?
Frankly, Satanism is a "reality religion".
We respect reality to include human nature as it is and as a part of nature overall.
Attempting to niche-define Satanism inside of any former perspective in history is an attempt to rewrite history.
Elements that were woven together to create Satanism by Anton LaVey in 1966 came from many minds and many cultures.
However the whole is more than the sum of its parts.
When these ideas were combined and codified, Satanism sprang to life, a living philosophy and religion.
Anton LaVey stated that Satanism was “a custard that can’t be nailed to the wall”.
Satanism is not limited by mere cultural or national borders.
As far as I understand COS supports a meritocraty.
I assume you meant to write "meritocracy".
If so, then the Satanic perspective is well summarized in the first Point of Pentagonal Revisionism: A Five-Point Program
