Without arguing about the ins and outs of racism and it's prevalence I think you are missing the point of the meme. Balance is not necessarily in-between two points of view.
One problem: the klan is far right and the blacks are moderate liberals. If both sides were moderate or extreme, then we would have usual centrist positions.
