A Tennessee hat shop has come under fire for selling “Not Vaccinated” stick-on patches modeled after the yellow stars Jews were forced to wear in Nazi-occupied Europe. “[P]atches are here!!” crowed the Instagram account of hatWRKS in Nashville, below a picture of an unidentified woman sporting the tasteless tchotchke. The advertisement was met with outrage on Twitter, with users calling for the store to be boycotted.
