Some quotes:
Imagine that white members of Congress, while walking to work, were surrounded by thousands of angry black people, one of whom proceeded to spit on one of those congressmen for not voting the way the black demonstrators desired. Would the protesters be seen as merely patriotic Americans voicing their opinions, or as an angry, potentially violent, and even insurrectionary mob?
Imagine a black political commentator suggesting that the only thing the guy who flew his plane into the Austin, Texas IRS building did wrong was not blowing up Fox News instead.
Imagine that black protesters at a large political rally were walking around with signs calling for the lynching of their congressional enemies.
In other words, imagine that even one-third of the anger and vitriol currently being hurled at President Obama, by folks who are almost exclusively white, were being aimed, instead, at a white president, by people of color. How many whites viewing the anger, the hatred, the contempt for that white president would then wax eloquent about free speech, and the glories of democracy? And how many would be calling for further crackdowns on thuggish behavior, and investigations into the radical agendas of those same people of color?
