We watched “While You Were Sleeping” a couple months ago. In it, a guy is accidentally pushed from a chicago train station ramp onto the tracks by a gang of yutes.
It was hilarious because the gang was white.
Aliens monitoring our TV and movies would be certain all the gangs were white. I recall an episode of Beverly Hills 90210 where some characters were chatting in a parking lot and a gang of white guys drove by and shot one of them in a drive-by. The victim was rushed to the hospital, where all of the dedicated emergency workers were black and/or female. The LAPD detective assigned to the case was a black man who vowed to catch the “scumbags” who had committed this heinous crime!
Then there’s the home security commercials that always, always show a white guy breaking in to the house.
