There seems to be some confusion as to what constitutes a racist tirade and what is merely an attempt to pierce the PC veil. Here's a primer:
This is a good example of mocking the PC establishment.* Note the presence of cleverness with a whiff (but only a whiff) of class.
This is a ham-fisted, insult-laden, poorly-researched failed attempt to be provocative by a cretin who's good at put downs but little else.
* Dead link in post was to story about how some "victim" group got up in arms about someone's use of the term "tar baby" to describe an intractable problem.
