People wondering what happened to common courtesy in America need look no further than the toxic national socialists who have taken over the democrat party.  If progressivist liberals don't want common courtesy, why bother extending it?  Twenty-five years ago progressivist democrats in the U.S. Senate, no less, attacked Robert Bork as extreme.  Google Robert Bork.  Progressivist liberals have not engaged in deep and thoughtful debate since.  Check out the comment section of this New York Times article.  The liberal commenters accept the lack of civility, claiming conservatives are much worse.  On the American Left, tolerance died twenty-five years ago and two wrongs make a right. --- http://www.nytimes.com/2011/10/22/opinion/nocera-the-ugliness-all-started-with-bork.html?_r=1
