Last year, a group at Ohio University called Students Teaching About Racism in Society (STARS) attracted attention with a series of posters depicting real-life minorities holding photographs of offensive costumes. The heading of the posters read "We're a culture, not a costume," and tagline to each striking image read "This is not who I am, and this is not okay."
This year, STARS is back with a variation on last year's poster; the tagline is "You wear the costume for one night. I wear the stigma for life."
Meanwhile, the influence of last year's poster has spread to other campuses; notably the University of Arizona, where the Native American Student Affairs has made its own homegrown version of it, with individuals telling their own stories.
First, an example of this year's STARS poster concept (last year, American Indians were one of the groups spotlighted; this year they were not):
Here are some examples of the posters created at the University of Arizona and posted to the Native American Student Affairs' Facebook page:
Finally, here's an image on the same theme -- it asks "Is your costume racist?" -- produced by students at Hampshire College.
