Maybe I'm just being particularly sensitive, but it seems to me that while people are complaining that your stereotypical "white" folks are erased, and replaced by "diversity", it seems to me the specific "diversity" here is "BIPOC" and your modal Mexican hispanic is being erased, despite being a larger percentage of the US population.
It's complicated because "Hispanic" is treated as an ethnicity, layered on top of race, and so the black people in the images could technically be Hispanic, for example, but the images are such cultural stereotypes, where are my brown people with sombreros and big mustaches?
