Final answer:
The proposed ban on Ethnic Studies classes in Arizona in 2010 was mainly due to concerns that they could promote racial resentment and conflict with American values, according to the lawmakers supporting the ban.
Step-by-step explanation:
The primary reason cited by lawmakers pushing for this ban was their belief that these courses could promote resentment towards other races, become divisive, and conflict with the teachings of American values.
Critics of the ban, however, argued that Ethnic Studies programs were valuable in teaching students about the contributions and experiences of varied ethnic groups within the U.S., often neglected in traditional curriculums.
Therefore, the debate was rooted in differing viewpoints on the role of education in addressing racial and ethnic diversity.
