My family watches CinemaSins. Instances of racial depictions are often tagged with a verbal, "That's racist!" when, sometimes, it's "race-ial" content or even the mere mention of race. "-ist/-ism" usually connotes negative orientations, or heavily biased presentations.
Can't imagine how to navigate this these days, but maybe there's a layer between.
Perhaps because sexism in this instance is completely acceptable? I'm not objecting to that, by the way.
