When talking about systemic racism, I find examples help. I tracked down this Supreme Court ruling. As an example of "systemic-racism" I can’t imagine a more convoluted, twisted, flat-out screwed up mind-set, but here it is.

NOTE: This is not something from the past. In 2015, just 6 years ago, the court heard yet another case revolving around this ruling.

You can find the full ruling here https://cite.case.law/cal-4th/60/1169/ I assure you the part regarding Christopher Columbus alone, is worth a read. For now, a few excerpts from this Supreme Court ruling.

THE PEOPLE, Respondent, v. GEORGE W. HALL

The appellant, a free white citizen of this State, was convicted of murder upon the testimony of Chinese witnesses. The point involved in this case, is the admissibility of such evidence.

...the Civil Practice Act provides, “No Indian or Negro shall be allowed to testify as a witness in any action in which a White person is a party.”

...the Criminal Act provides, “No Black, or Mulatto person, or Indian shall be allowed to give evidence in favor of, or against a White man.”

In using the words “no black or mulatto person, or Indian shall be allowed to give evidence for or against a white person,” the Legislature, if any intention can be ascribed to it, adopted the most comprehensive terms to embrace every known class or shade of color, as the apparent design was to protect the white person from the influence of all testimony other than that of persons of the same caste. The use of these terms must, by every sound rule of construction, exclude every one who is not of white blood.

The appellant, a free white citizen of this State, was convicted of murder upon the testimony of Chinese witnesses . . .

For these reasons, we are of opinion that the testimony was inadmissible.

The judgment is reversed and the cause remanded.
