I think you may be confusing white supremacy with white privilege.
No black man could have wandered around town with a rifle strapped to his side without being arrested--let's be honest here.
Removing unconscious bias is a good thing. We all need to do it.
I do agree that some people take it a bit far, but there is still no doubt that the biggest threat to our country right now is organized white supremacists who promote violence. That's straight from the FBI, btw--I didn't make that up.
