What is Ankharism? Google does not find anyone but you using this word. I suspect you have fabricated an English word by transliterating from another language, but I cannot trace it. Somewhere you talk about Cambodia. Perhaps you mean Angkorism, a rare name for the ideology of the Khmer Rouge, after the Angkor Empire?

(There is also the Ankharite, named after the Egyptian Ankh, which may be displacing the term you use.)
