Black racism is studied as well; if you'd like some links to articles I'd be happy to give you them.
Yes, please.
Here are three pieces on black racism (two papers and one documentary)-

"Before we begin our examination of racism in the African American academic community it must be stated clearly that the major victims of racism in America have been people of color, particularly people of African descent. . . . In America, racism in the African American community harms the civil rights movement.
. . .
But the dangers of [black] racism is much broader and less obvious than the above example would imply. The Black racist are embraced by the white racist. They feed off of each other and encourage each other. They also influence the most talented young Blacks in American colleges, encouraging their alienation. The message they sell is that there is no solution to racism."

" . . . The Clarks found that Black children often preferred the white doll and drawing, and frequently colored the line drawing of the child a shade lighter than their own skin. Samples of the children's responses illustrated that they viewed white as good and pretty, but black as bad and ugly."

(synopsys)
When Davis repeated the experiment 15 out of 21 children also choose the white dolls over the black, giving similar reasons as the original subjects, associating white with being pretty or good and black with ugly or bad. The dolls used in the documentary were identical except for skin colour.
For example, I googled "black racism election poll" (no quotes) and all of the first 10 links were about white racism, not black racism. Then I put "black racism" in quotes and it didn't help. "Anti-white racism" with "election poll" at least got the subject to the right thing, but didn't really provide relevant polls on the election.
Understandable. Since most racism in America has been towards blacks, that's mostly what is studied. You'd have the same problem if you tried to research the problems billionaires have getting access to low-cost health care.
