The US is not falling apart in any context whatsoever. The people wanting to leave are throwing little more than a hissy fit. Very few of them seem to have truly considered what would happen if they were to try to leave the Union, the government would never allow that to happen. If they chose to fight their way out of the Union they would lose, and those who supported the movement would be charged with treason or even possibly dragged off under the NDAA.
Just treat it as it is, people throwing a tantrum because they hate the rest of the country's choice for President. Let them suck on their thumbs while listening to Glenn Beck and Sean Hannity about the evil muslim socialist trying to destroy white America.
