Wake up, chicken little. The sky ain't falling. Someone wants you to believe that, though, because fear is a powerful motivator for some folks.
This country has weathered George W. Bush, Richard Nixon, and Jimmy Carter. We've survived being torn apart by civil war, World Wars 1&2, slavery, the racial upheaval of the 1950s-60s, Vietnam, and giving the vote to women. We'll muddle through like we always do, regardless of who gets elected.
There is plenty of irony in using a fear-based argument (ZOMG, the country is being destroyed!!!) and then calling other people cowards and pussies for being unswayed by it.
