The movie "Falling Down" notwithstanding, "angry white man" isn't a pernicious stereotype, and "angry black man" is. I'm neighbors with more than one professional black man who has told me they have to be extra careful in the workplace, because any frustration they express will be amplified by the perception of their (overwhelmingly white) coworkers. The first time I heard this, I didn't understand and had to have it explained to me. It's a thing.
