Without being a jerk about it, take off the American exceptionalist glasses we're all "gifted" growing up in this society and ask yourself, how do you think nationalism militia violence and terrorism happen in other places? What DO they look like when they start? If you want me to agree that these folks probably can't take over the country, I'll be happy to do that. But there's a lot more ways to lose this horrifying game than chud rush seizes the capital.
