Here’s another excerpt from Sweet Land of Liberty on the shift in White Northern racial attitudes after World War II:
“The struggle over equality in education had paradoxical effects on whites. On one hand, white attitudes toward school integration changed dramatically in the years following World War II. In 1942, a Gallup poll showed that 40 percent of northern whites agreed with school integration; by 1956, two years after the Brown decision, the figure had risen to 60 percent; by 1963, another polling firm discovered that 75 percent of northern whites agreed with Brown.”
Note: Among other things, we have seen how the Northern states passed fair employment practices laws and anti-discrimination laws that covered public accommodations after World War II. At the same time, White Northerners were changing their views on school segregation and racial equality.
