I honestly don’t think racism is the root source of the hatred. It’s more a of an “otherism.”

They hate and are scared by and lash out at anything that threatens to push at their little bubble of insecurities. Urban progressives, well-educated college professors, the French, Mexicans, South Americans.

Racism goes hand in hand with this, so they tend to be racists and spout racists views, but they would be just as hateful to pretty much any Democratic president. They would just pick different ways of being hateful.
