Wow! Where did you get this strange data? I never read anything like it in the dozens of books I have read about the affair. The latest book is "The New Dealer's War'" in which the forced removal of the Japanese from California was the result of racist hostility and jealousy. Even J. Edgar Hoover was opposed to the incarceration of the Japanese/American citizens. FDR forced the issue, however and it was done.
My uncle was a camp commander and he never once mentioned any anti-Americans in the camps. Quite the contrary, he came to admire them and they liked him. There were camps here in Utah and they flew the flag and celebrated the 4th of July as fervently as anyone else. There were even more Japanese in Hawaii, but they were not removed. Futhermore, how come so many young Japanese in the camps joined the army and fought extremely well, winning more medals per unit than any other in WW II?
Amazing, isn't it?
Of course, I am starting to have my own suspicions as to why Michelle Malkin would defend internment camps and rehabilitate the entire notion of internment in general. I think she aims to see it applied elsewhere.
