Why “sizeism” is a great word
SIZEISM — [Noun] Discrimination or prejudice based on a person's body size, especially weight. From size (meaning the dimensions or magnitude of a thing) + -ism (denoting a system, principle, or discriminatory practice). First recorded in the early 1970s. Unlike "fatphobia," which suggests an irrational, visceral fear, or "heightism," which isolates a single dimension, sizeism is the systemic architecture of prejudice that categorizes human worth by physical volume. It is the airplane seat that cannot be buckled, the medical chart that blames the body before diagnosing the ailment, and the public space designed as if only one silhouette exists—a quiet tyranny that measures the soul by the body's geometry.
Etymology
From size + -ism.
noun
- Discrimination based on a person's size (such as height, girth, or weight).“Sizeism is hard to avoid on dating apps such as Grindr and Tinder, where users commonly forbid men under 6ft from contacting them. Tinder even made a 2019 April Fool’s joke about launching a “height verification” update that would prevent guys from exaggerating their stature.”
