The Origins of White Supremacy in the United States

The term white supremacy seems to me that it's just being cast around without any serious consideration of its origins and its meaning. And so i would like you to address, as best you can, the origins of white supremacy in the united states. I believe that it begins with the old south; we can see aches by southern politicians that were leading the south. But my point is that when you have a large majority, it is suspicious. It always is going to be blood and soil ive.
