Question

what does "One-third of the population of the South is of the Negro race. No enterprise seeking the material, civil, or moral welfare of this section can disregard this element of our population and reach the highest success." mean?  

(please answer ASAP)

Answer 1

1/3 of the people in the south are black. Nobody can deny this and be successful.

(That’s kind of blunt, but it gets the point across.)
