Dividing people by concocting "awareness" of how food defines race and gender (another misanthropic concept that challenges nature) is academia creating culture not studying it.
At first blush, it's hard to determine if "food justice" refers to weighing the equality of edible components on one's plate, how what is eaten affects one's sense of justice, if food types and distribution indicates human equality/inequality, or...?
Actually, it comes down to an absurd, and flimsy concept, yet it's being instituted as a minor field of study at one of the United States' foremost agricultural schools, Oregon State University. Titled "Food in Culture and Social Justice," the degree is faddish at best and pointless at the least.
