ATHENS, Ohio – Some students at Ohio University are taking in upon themselves to educate their classmates on how to enjoy a politically correct Halloween with a campaign aimed at curbing “culturally appropriative” costumes.

One of the latest campaign posters for OU’s Students Teaching About Racism in Society, commonly referred to as OU STARS, is aimed at killing any costume that makes light of the Black Lives Matter movement.

It features a black woman in a BLM shirt – fist raised, of course – with two goofballs in the background dressed up as a cop and Black Lives Matter protestor. The cop is casually pointing his obviously fake gun at the white woman, in blackface, with a sign that reads #ALL LIVES MATTER.

“We’re A Culture, Not A Costume,” the poster reads. “My fight is not your costume.”

“’We’re A Culture Not A Costume’ began in response to the large block party at Ohio University every Halloween,” OU STARS president Maile Nguyen told NBC News. “We feel that culturally appropriative costumes alienate and exotify certain students on our campus, and (we) wanted to educate people on the harmful effects of enforcing negative stereotypes of minorities.”

The STARS program has been around since the late 80s, and began to gain traction in a more politically correct world in 2011 with a campaign featuring costumes of racial stereotypes and the tagline “This I not who I am and this is not OK.”

According to the news site:

Other messages that have been featured in subsequent years include, “You wear the costume for one night, I wear the stigma for life,” “You think it’s harmless, but you’re not the target,” and “When this is how the world sees you, it’s just not funny.” Not limiting themselves to ethnic and racial stereotypes, the organization has also critiqued costumes of transgender and hillbilly stereotypes.

The STARS website describes the group as “a peer education organization providing multicultural workshops at Ohio University,” and features the group’s campaigns.

“STARS is a group dedicated to the preservation of racism through education and awareness!” according to the site, which was apparently last updated for the fall 2013 semester.

On the group’s Facebook page, it’s a steady stream of advice for students about the dos and don’ts of proper Halloween costume protocol.

“Is your costume racist?” one post reads. “check yourself and your friends – your costume can have unintended negative effects!”

It encourages students to ask themselves a series of questions.

“Is my costume supposed to be funny? Is the humor based on making fun of real people, human traits, or cultures?

“Does my costume represent a culture that is not my own?

“Does my costume reduce cultural differences to jokes or stereotypes?

“Does my costume packaging include the words ‘traditional,’ ‘ethnic,’ ‘colonial,’ ‘authentic,’ or ‘tribal’?

“Does my costume perpetuate stereotypes, misinformation, or historical and cultural inaccuracies?”

OU students have a lot to consider, and Nguyen said OU STARS are going all out in 2016 to make sure all students on campus have a culturally sensitive and politically correct Halloween.

“This year, we really wanted to pay tribute to the BLM movement, and show that racism still exists,” she told NBC News. “For the past few weeks, we have been planning, editing, and distributing our latest poster as well as strengthening our diversity trainings that we provide to other student organizations.”
