Maybe you should do the math or, better yet, open your eyes to take in the evidence. The most significant systemic racism in America is manifest in the Affirmative Action programs that give preferential treatment to Black Americans. These have been going on for 50 years. Being Black gets you 150 points on your SAT score when it comes to college admissions. It gets you recruited and gets you hired more often than an Asian or White person with the same qualifications. Overt racial discrimination against Blacks is illegal on the job and in public accommodations, snd has been since the 1960s. If you know of any instances of actual discrimination you can file an EEOC complaint or file suit in court. People may harbor all kinds of prejudices, but they cannot treat someone unfairly on account of race without running afoul of our laws and regulations.
There is no systemic bias against Blacks. There is inequality in outcomes in a host of areas. Why is that not evidence of bias? Here’s an example. A smaller percentage of Blacks get admitted to college. One major reason for that is that a smaller percentage apply to college. Similarly, the percentage of STEM majors who are female is lower than the percentage who are male. This happens most likely because relatively fewer females elect to pursue STEM subject majors.
The larger point is that the “math” of unequal outcomes doesn’t prove or even indicate systemic racism against POC. You need a pattern of explicit unequal or unfair treatment of individuals on account of race to make the case for systemic racism. But you don’t have any evidence of that.
