You’re talking about reverse racism:
Reverse racism or reverse discrimination is the concept that affirmative action and similar color-conscious programs for redressing racial inequality are a form of anti-white racism. The concept is often associated with conservative social movements and the belief that social and economic gains by black people in the United States and elsewhere cause disadvantages for white people.
Belief in reverse racism is widespread in the United States; however, there is little to no empirical evidence that white Americans suffer systemic discrimination. Racial and ethnic minorities generally lack the power to damage the interests of whites, who remain the dominant group in the U.S. Claims of reverse racism tend to ignore such disparities in the exercise of power and authority, which scholars argue constitute an essential component of racism.
Allegations of reverse racism by opponents of affirmative-action policies began to emerge prominently in the 1970s and have formed part of a racial backlash against social gains by people of color. While the U.S. dominates the debate over the issue, the concept of reverse racism has been used internationally to some extent wherever white supremacy has diminished, such as in post-apartheid South Africa.
