It is interesting that the Left with its frequent attacks on the Right for being racist, turns around and denigrates people based on race. I believe that is what is meant by the term 'racist.' 

Imagine what the 'fall out' would be if some one referred to the angry, or fat, or lazy, or (insert any term) Black men, or Native men, of homosexual men. 

When one cannot defend ones political stance, slurs must substitute for reasoned debate. The degradation of civil discourse is a characteristic of most political discussions these days, and is unfortunately used by all, left, right, center, and off the wall.
