as you see the reaction of the RW to the Martin murder, realize they are expressing their fears.
When they attack the president on race, white Priviledge.
You see, a black president is the worst nightmare to them, a man shooting a kid, for the color of his skin...stand your ground...
In effect what you are seeing are the racial tensions of a group of people who are afraid of what innevitably will come, a multicultural society where curry and barbeque mix, and tacos and grits are there.
So as you listen, or read, reactions to this, realize, you are watching deep racial fears of people who really cannot understand, there are no inferior people, and race, in a scientific way, does not exist. It is not just Stormfront or our spelunking "friends." This fear is deep seated, and actually is part of our cheap labor ideologies. If there are no inferior people, you mean we have to pay them the same? The other side if the coin were riots in Colonial America to protest the use of slaves, taking jobs away from white freemen. In the modern day, the expulsion of Mexicans during the Depression, or laws such as Arizona.
This is what we are seeing, a very toxic brew...and yes, white Priviledge and a caste system are very real, as well as the social tensions that come with it.
