They not only use certain code words, but they also use demographic info and statistics to divide people and alarm them.
I can give 2 examples of how the main stream media puts out information to divide the nation along racial lines.
1. Every year they put out information about how the White population of America is declining and the Black and Latino population is increasing.
What is the purpose for constantly feeding the public this information unless they are trying to signal those who don't like these facts to take action?
I know for a fact that this belief that the Black/Brown population is crowding out the White population is the MAIN factor behind the anti-abortion stance so many White conservatives have taken in recent decades.
If abortion clinics were only located in the inner cities, you wouldn't hear a peep out of them.
2. After the recent election, the media constantly breaks down who voted for whom along racial lines making a point to show that while most Whites voted for Romney..... Blacks, Latinos and Asians voted overwhelmingly for Obama thus securing his presidency.
They've been putting this information out over and over again as if to tell Whites, "If you don't want this to keep happening over and over you had better make haste and do something about it"
To some, this information makes it look as if people of color are "conspiring" against Whites.
