I think it’s important to differentiate systemic racism from bigotry. There are some people who have a definition of “racism” that actually means “systemic racism,” and they make a more compelling case that “racism against white people” doesn’t exist.

I’m of the opinion that systemic racism against white people is pretty rare, but you can find it in niche communities, not as much society as a whole. I also think of systemic racism as being about inequity rather than inequality; but if you were to consider it as being about inequality instead of inequity, then you could make a case that e.g. affirmative action is systemic racism against white people.

A lot of this is semantics, which is a distraction from real problem solving.
