Racism is "a prejudice, discrimination, or antagonism directed against someone of a different race based on the belief that one's own race is superior." (from the Oxford Languages)
FROM THE USCCB
...Some among us may want to believe that our country has moved beyond the reality of racism that has so profoundly stained its past, or that racism does not involve us. Almost every day, news headlines demonstrate that our country’s “original sin” of racism continues to impact the lives of many Americans, many of them Catholic—particularly those who belong to the African American, Hispanic/Latino, or Native American communities. There are signs that racism’s legacies remain prevalent in many systemic inequalities that have deep impact on people of color. The bishops write, “Racism can only end if we contend with the policies and institutional barriers that perpetuate and preserve the inequality—economic and social—that we still see all around us.” (from "Open Wide Our Hearts Bulletin Insert")
