Big up-vote! Years ago I submitted a meme to the politics stream and in it depicted a gang in San Francisco. I had searched the internet under 'San Francisco gangs' which turned out to Hispanic / black people. I posted the meme w/ one of the pictures and it got rejected for racism!
I searched again under just 'gangs' and found gang membership was predominantly pictured as minority groups. I finally found a pic of a gang with only their backs shown and one could not tell the color of their skin. I substituted that pic and resubmitted the same meme and it was approved.
You are on target on this one, ChadAndrew, as it has happened time and time again in the politics stream.
