When I first saw this cartoon, I initially thought it was drawn by a conservative trying to show how obsessed the liberals have been on this issue.
Its an easy target—a symbol they can trash to impose their way—next they will say the Redsocks are racists, or the Cowboys! Like the Confederate Flag—its easy to spin it as racist, KKK, symbol (even if it wasn’t). They have to keep up the pressure to reform—keep the pot boiling. Its just their way.
