Via Bug Girl, who has a post of her own about Halloween costumes, comes this campaign to get people to think a little bit harder about their costumes this year.
From the blog post:
These incredible posters were created by the student organization at Ohio University called Students Teaching Against Racism (STARS). Amazingly, these posters became popular over Tumblr on their president’s blog site (here). Their mission is “to educate and facilitate discussion about racism and to promote racial harmony and to create a safe, non-threatening environment to allow participants to feel comfortable to express their feelings.”
There are five posters. You really should see them all.
Update: If you still have questions after reading that post, I suggest you try Crommunist’s FAQ on the topic.
