Not unlike what we have going on in the Coli, everything gets compartmentalized. For instance, a lot of white republicans may be very sympathetic to the Mike Brown situation. You know how the media elite can exploit that? A Double whammy. Downplay the fact that the protesters all have different backgrounds and stand on opposite sides politically, and label them all liberals. This means if other people don't dislike them for supporting a kid, Mike Brown, who was made to be a bad guy, they can dislike them for being a different political ideology.
While we argue about race, and rightfully so, there is a contingent that isn't interested in race itself, but the money it can get by playing both sides. Some people in this life are purely motivated by the green, and don't sweat race. They will stir the pot to whomever will get the most ROI.
