Racism in America...NO, it's not OK because its always been or didn't mean it

The good professor has decided to approach the most sensitive of issues that being the sorry state of race relation in America by using some of the lamest, most self-serving or just plain political (nuff said) excuses used since the civil rights movement, some dating back to the nineteenth century.  Who's responsible is the syustem and the control, which is and always has-been forever, with brief periods of common sense followed by catostrophic change and repeat...it's like America has to wash it's hair occasionally, keeps the conservatives out.  Will your intrepid host continue on any number of topics, sometimes even forgotten in mid-thought and you are assured that someone, somewhere, somehow is going to get toasted, maybe evan multiples.
