I think one man is just as good as another so long as he's honest and decent and not a nigger or a Chinaman. Uncle Wills says that the Lord made a white man from dust, a nigger from mud, and then threw what was left and it came down a Chinaman. He does hate Chinese and Japs. So do I. It is race prejudice I guess. But I am strongly of the opinion that negroes ought to be in Arica, yellow men in Asia, and white men in Europe and America.
