...yes, this one was quite transparent...and NASCAR et al have lost some credibility. As for my friends across the pond, may I interject a bit here please...and Mod, please note this is motorsport related.
The confederate flag banned from NASCAR is not the confederate flag...but actually a confederate battle banner/naval jack (there is some nuance to this statement, but such can be correctly stated). The "stars and bars" as it came to be called, evolved into a number of symbolisms. One such relation was that associated with the KKK...and hence its numerous calls for removal. The other has to do with the "rebel" connotation...not a "confederate" connotation. The "rebel" association has to do with the manufacture of illegal whiskey in the deep south (even today, some areas are "dry"). These "rebels" souped up their cars and operated a "Fast and Furious" style alcohol delivery ring...running from and out running the Federal "revenuers". They called themselves"rebels" and proudly displayed the "rebel" flag in defiance to Federal law enforcement. These whiskey runners and their cars became the first "stock car" racers and the first "stock cars".
So yes, the flag has racist overtones...but also yes, the flag can have no racial overtones.
