I was recently reading a long article about the Red Scare of the early 1920s, with the Palmer Raids and the mass deportations that followed. So for the good ole US of A, it's a case of 'been there, done that.' In fact we once had a political divide become so heated some of the states tried to leave and form their own country. That led to an actual state of warfare between the various states. Hundreds of thousands of Americans lost their lives.
My point is, it's been worse. A lot worse. As Barack Obama has said, we take two steps forward and then one step back. He said something along the lines, 'We'll survive this and be stronger for it. Right now things are tough. But life changes. We'll go on. Don't lose hope.'
