Native Americans had the least amount of prejudice directed toward them

Explanation:

Native Americans faced much prejudice in the society. They were subjugated socially. They were not given the priority in any of the federal scheme. They were also ill-treated on the basis of racism and ethnicity. Native Americans are the indigenous people of America.
