They aren't..but the looneys they inspire most certainly are..
Not really.
A truly effective civil war takes planning.
It takes organizing and it takes money.
IN a land where nearly 1 million people have secret security clearances, and multiples of that number actually work either for the FEDERAL government or are well connected in state police states, organizing a an effective cabal against the state is pretty risky business.
If there's going to be a civil war, its going to come from within the ranks of the very people who are now in charge of society.
Some splinter group of the folks now in power would be the more likely source of a government overthrow.
And if that happened, the government they would impose would NOT BE that freedom loving, Libertopian utopia that most disaffected gun queer Americans are dreaming of.
Some Americans actually posit the possibility that that coup d' etat already happened, ya know.
When JFK was murdered.
And while I do not subscribe to that theory, I must say that the USA changed a lot since that time.
