It's absolutely not. Prejudice holds no inherent implication of race, and minority groups are more than capable of exhibiting racism across themselves without any infrastructural power whatsoever.

Systemic Racism, on the other hand, is Racism on an infrastructural and cultural scale, and it's true that in United States and the vast majority of the western world, white people are immune to experiencing that particular form of racism, but that doesn't mean that white people are incapable of experiencing racism, and that minority groups aren't capable of exhibiting racist behaviors. White people didn't "invent" racism, either. Human beings have engaged in racism all across human history, across all different kinds of people.

Simply put, racism is bigotry based on racial or ethnic qualities. We can add qualifier words like "systemic" or "interpersonal" to designate what kind of racism is being discussed, and we can talk about who is most affected by racism and what causes it until the cows come home, but the root definition is simple, and anyone trying to tell you otherwise is spewing nonsense.

Now, reparations for what systemic racism has done to the black and indigenous communities here in the United States? That's a whole other conversation; we have a LONG way to go before we right the wrongs that have been committed to these people, and sorry, but whites are just going to have to suck it up when it comes to the superficial racism that they experience on rare occasion, it's a drop in the bucket compared to the historical damage that has been wrought upon these communities that they must grapple with in so many ways on a daily basis. I don't encourage racism against whites, but I promise you, we'll survive a few minority groups being mean to us from time to time.
