That's a major criticism I have of the crusaders against "systemic racism." While I think the term is intended to capture the accumulated, "death by a thousand cuts" set of disadvantages that are faced by marginalized groups, it characterizes the problem in such a way that it makes it seem intractable. This is a perfect framing for politicians and activists, whose focus (IMHO) is on getting people mobilized by describing/raising awareness about problems, rather than actually solving them.
To me, when somebody describes specific examples of "systemic racism", I am immediately able to suddenly identify specific actions that can be taken to address each tractable problem. Replace "America is inherently racist" with "End Qualified Immunity" and "ensure public schools share funding across regions", etc. I think framing things like this makes the problems more solvable and far less politically useful for the demagogues.
