However, “swirl” conjures images of chocolate melting into vanilla – and this is where ice cream metaphors fall horribly short. On her high-traffic dating site Beyond Black & White, Karazin (who’s happily married to a white man) makes the case for “swirling” based on statistics that are the product of systemic inequalities, such as low marriage rates between African-Americans. Swirlr, which is about as edgy as an episode of Joe Millionaire, features awkward bowling dates in which spirited women named Quintana gravitate towards brooding jocks called Rocky.

Karazin’s app might ask us to “date different” but her project still reflects a culture that uses the language of cosmopolitanism to push a version of diversity with whiteness at its heart. If the world was really post-racial, we wouldn’t celebrate interracial couples for being interracial. Love depends on feelings that occur entirely beneath the skin.
