Why is the George Zimmerman/Trayvon Martin case relevant to white-on-black killings? Zimmerman is 3/8 Hispanic, 1/8 black, and 1/2 white. Historically people who were one-eighth black were counted as black, but the media labeled Zimmerman as white because it fit their agenda to do so.
The media seized upon the ease of the public mind in accepting Zimmerman as white because they wanted to promote the "white man kills black boy" meme.
They succeeded in doing so by ignoring/not reporting the facts of the situation and created a martyr where none would have otherwise existed.
The stupid liberal mind continues the myth.
It's why we call them stupid liberals.
They wanted a cause, they created one out of whole cloth...and now they believe it as though it came straight from the Gospel.
