I know exactly what the origin is (and as somebody commented below, it predates the incident you refer to). I also used it because it aptly describes people whose exaggerated sense of entitlement and privilege overshadows their desire to think critically. My daughter saw this in person, where a woman was mad at people at the butcher section of the grocery store, calling woman who bought a whole chicken an 'animal murderer'. Plot twist: the very same woman had chicken breasts and thighs in her cart, but because they were not a whole chicken, she disassociated them from the animal they came from. I rest my case.
