In the 61 years I have been on this planet I have never seen such hostility towards a man. Although there was some noise when Obama came into office, it really didn't start till 12-18 months into his term. Even though the Tea Party movement was founded at the end of February 2009, it really didn't pick up traction till 2010.
I truly fear we are moving into a very hostile period in the States. I suspect as spring replaces winter we will see more and more civil discourse.
