Not quite. White supremacists also overlap with the whole "rebel" and "rugged individualist" and "prepper" mindsets. Which are fundamentally incompatible with central authority in any way.
I guess you could really split white supremacists into two camps, the authoritarian and anti-authoritarian camps. You'll find a lot of the latter in prison gangs, and a lot of the former among the police. The two don't always get along, is my point. They both hate minorities, but they're otherwise quite different.
