If "racial slurs" keep you from considering accounts and documents out of moral outrage, you ARE the sort of person who could claim that Truman was wrong to use the bombs, and you would be wrong.
PS, never EVER read Mark Twain, it would offend your superior morality.
Ain't that the truth. I'm amazed the liberals still allow it in school.
I read Huck Finn to my son when he was 4. Changed the "n" word to slave and it read just fine!
