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.
I’m not sure I fully appreciate the point your making with breaking down the idea “America is inherently racist.” Outside of Twitter I’ve encountered exactly zero conversations that start and immediately end with such a statement. Of course things like qualified immunity and equitable education come into play - these topics have been heavily discussed in the public sphere for decades! To link them in this case to speak to a community’s broader experience seems both reasonable and necessary.
For a light hearted analogy — say I get a burrito from a taqueria on Monday and shit my pants and then go back Tuesday for tacos and shit myself again. When I’m retelling that story on Wednesday over sushi, you’d better believe I’m using the name of the restaurant.
And there seem to be quite a lot of people willing to implement said solutions.
