I see the sign at the entrance of the thrift store — “GYPSIE’S SPECIAL: 75% OFF EVERYTHING” — and, automatically, my blood is boiling, but I am silent. It’s not the first time that I’ve seen signs like it. From flat-out racism to the encouragement of well-meant, but nonetheless offensive, stereotypes I’ve already heard everything in reference to my people and, previously, there have been few instances, outside of college classrooms, where I felt safe enough to speak out against such things.
