Depends who you talk to. I knew some avid conservative media consumers who, when Obama was first elected, were sitting around with their friends talking about* how they were going to buy weapons to "defend themselves" from black people, who were obviously now going to have a revolution (or just mass, violent riots - it was unclear). They were hardly alone in that, because this was the message being sent out on conservative media. Now it's more about evil immigrants, but it's still there.
*I assume they actually did it - I cut off all contact, direct and indirect, immediately after.
