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.
