Going back to the original post here (specifically the title of the post) - no one "injected" (or even "injetted" as you said) RACE into the review of the show. The casting was noted, just as any critic would do. Period.
Maybe your premise needs to be that the PRODUCTION "injets" [sic] race into the show with its casting. But why are you blaming the REVIEWER? I don't understand that at all.
