A shockingly racist "tribute" to Martin Luther King

Last week was the 50th anniversary of Martin Luther King's famous "I have a dream" speech, arguably the most important moment in the struggle for equal rights for blacks in the face of segregation and denial of rights - especially the right to vote. As a way to "celebrate" the anniversary of this speech, People for the Ethical Treatment of Animals posted a shockingly racist picture to their Google Plus page:

Surely the folks at PETA know that racists have a long history of comparing blacks (especially black men) to primates. Black men were dehumanized as animalistic, rabidly sexual creatures who were a threat to innocent white women. This led to the murder of many black men since Reconstruction, including the horrific murder of Emmett Till - who was 14 years old when he was tortured to death by a gang of racists. This is what they did to him:

That is why it is so despicable for PETA to equate "animal rights" to the struggle for civil rights, especially using an image of primates with a quote from Dr. King superimposed over it.
