Why should he do anything for black Americans, that he doesn’t do for white Americans or Asian Americans etc.?
Context means so much doesn’t it :-)
He might more cleverly say he would help them by not doing anything special to help them.
..because every single time the white man has tried to do something special to help the black man, he’s muffed it somehow.
Because God never wanted people to be looked at in terms of a “race” at all (other than the biblical race of the Jews, which actually encompasses people of all secular “races”).
White people got this hint better than others, possibly because white people look more similar than non white people do. There is less to hang a racial hat upon with white people.
