You must be either too young, or haven’t studied WWII history. Rosie the Riveter was regarded as a heroine because she entered the work force to build airplanes, and whatever was needed to help our boys fight. We won, BTW, in case you need to be reminded. Rosa Parks proved a point and got a free ride which has not ever stopped, and probably never will.
The writer is saying that CHAMELEON Hillary CHANGES for every audience! She WAS the SAVIOR of the Blacks...hence, Rosa, then she was a WHISKEY SWIGGING WORKING GAL ...hence, Rosie. Geesh....
