As SheCodes of Black Women Vote explains:
What makes some white people think that 'humorous' lynching references are acceptable? Would they applaud imagery of Joe Leiberman's wife being tortured and cooked alive in a Nazi oven in response to a slip of the tongue she may have made? Would they accept a picture of Laura Bush hanging from a gallows?...I might add that presenting a woman's torture in a sexual way is nausea-inducing as well. Kos has taken the image down, which is good and hopefully shows he's listening to criticism. But, wow, guys - you really need to be better than that.
To certain people, this picture is cute, 'edgy', and 'ironic'. They are 'defending' the middle class by 'pointing out' racism. Underneath it all, as usual, the black woman's degradation is simply a tool to be exploited to further their own agendas.
SheCodes goes on to call for the formation of an Anti-Defamation League and Political Action Committee for and by African American women. If you are an African American female, go check it out. For those of us outside that community, this is yet another in a tragically long line wake-up calls. We need to be better allies, and check ourselves to make sure that we aren't hurting people with backgrounds different from ours.
UPDATE: The original screen capture can be seen here, but it strikes me as odd that Kos himself hasn't addressed this. I can't decide if I've been punked and the whole thing was created as a smear campaign in the first place, or if this is an uncharacteristic refusal to take responsibility. Does anyone know any more about this story?
