What a silly post.  Your picture of Blacks in the South "laughing and singing" and honoring the "Old South" of slavery and segregation is laughable.  To be sure, over decades of slavery and segregation, Blacks learned (many of them "the hard way") to stay "in their place". To passively accept Second Class Citizenship, to drink from the "Colored Only" drinking fountain, to sit "in the back of the bus", to accept being called "N##@@" or "boy", to attend inferior, segregated schools, to be unable to eat in restaurants or stay in hotels, and all the other indignities that racial discrimination inflicted on them.  Oh, yes, Earl, they really "fly that Confederate flag" in memory of those wonderful years.  What an insulting post.  

The gas station?  Guess what, sometimes living with integrity and honoring human values is  bit inconvenience.  Personally, I'll run out of gas before I'd buy gas from a racist.  What you do is your business, What Mr. Dalton, I or anyone else chooses to do is ours
