No, I know everyone experiences racism. You've kind of admitted your own bias in this discussion now. Black people can be racist. You say "we aren't." There was never a generalization to which you could apply "we" but it is clear you likely consider all white people to be racist. Even those white people who are subject to these supposed power structures that make them invulnerable to racism.

A white student in a majority black school with black teachers and administration can experience "structural racism" in the same vein that a black person can in a similar situation. There is no delineation of the sociological definition so even then you have to accept black people can be racist. How about a white person in an African country? This exposes many of the problems with the blanket "black people can't be racist" statement. Black people do hold power in many places around the world including within America and wield that power over some white people. Your statements just further support the damage your beliefs can cause other people when you ignore all of this nuance and bring it back to "we can't be racist."

Black people can be, and some are, racist on an individual level and they can be, and sometimes are, racist in the new sociologically defined sense.

One example might be Ethiopia.

This is a nation that never experienced colonization but widely engage in the slave trade going back to the 1400s. A white person in Ethiopia has none of the "structural power" and so on.

the systemic oppression of a racial group to the social, economic, and political advantage of another

Ethiopia has a lengthy history of racism towards many different ethnic groups. A white person there experiences systemic racism by black people. Again, black people can be racist.
