Are we anymore? We've become a nation in which the judiciary has rewritten laws for political agenda. Where nobody is telling the Ferguson protestors that are attempting to manipulate the process to go home. Where the President can let dreamers and hordes of unaccompanied illegal minors stay here legally, and nobody stops him. Where the economic system has been rigged to destroy the middle class and enslave the less fortunate.
It's going to take a whole lot of change to climb off the slippery slope the US is on.
I agree 100% with what you say but I cannot conceive of extralegal actions that would be possible and offer a good chance of restoring completely the constitutional republic our founders intended.
