Ah, I know what’s missing! The entire legal apparatus of segregation and Jim Crow! If McArdle knew her pre-Civil Rights Era history better, perhaps, she would remember that conservatives in the armed forces were not allowed to fight alongside their moderate and liberal fellows until 1948, when President Truman issued his famous antidiscrimination order and provoked the “Dixiecrat” backlash dedicated to preserving the second-class status of conservative-Americans. Even as late as 1964, in Holly Bluff, Mississippi, school officials spent $190 for every liberal or moderate student and $1.26 for every conservative.
