At some point you have to abandon the canard that it's just about Obama's race, and acknowledge that these are manifestations of Obama's distance from the priorities and ideology of most Americans.
Marie Antoinette was not black. The angry mob was not using code to call her the N-word. It was her elitism and callousness they hated.
Liberals who bemoan discrimination, intolerance, restraint of Constitutional freedoms, and promotion of hatred toward various abberant minorities, have absolutely no problem with discriminating against, being intolerant of, restricting Constitutional freedoms of, and directing hate-filled scapegoat rhetoric against conservatives.
EXACTLY what they accuse Republicans/conservatives of doing, is EXACTLY what liberals/Democrats do themselves, to those who oppose their beliefs.
