I have to admit, I'd never heard of ARME before reading this article. But through some research at k12academics.com -- I found the following summary:

***

"Discussion of the mathematical knowledge of ancient civilizations outside of Europe, and non-European contributions to mathematical knowledge and discovery.

The avoidance of racial stereotyping when forming and communicating expectations of pupils' attainments in mathematics.

The avoidance of racial stereotypes or cultural bias in classroom materials, textbooks, coursework topics and examination questions."

***

None of this sounds REMOTELY objectionable, when it comes to enhancing public school curriculums; in fact, it sounds like an intentional fusion of mathematic and multicultural history...possibly in a format that could be team-taught, where feasible.
