I'm aware that the federal US government apologised to and compensated Japanese-Americans who were interned or their descendants, and that there's a play currently in broadway about internment.
On the other hand, a couple of politicians have referred approvingly to internment recently, and conservative writer Michelle Malkin wrote In Defense of Internment.
I have a suspicion that pro-internment sentiment may exist in what Australian politician Cory Bernardi calls The Whisper Zone, views that are held by some people that are generally not publicly expressed.
I tried searching for opinion polling on internment, as I know opinion polls are still held about the US's atomic bombing of Hiroshima and Nagasaki, but I only found information about opinion polling performed at the time internment was in place. (I was a little surprised - I didn't know opinion polling about policies existed back then)
How widespread nowadays is sentiment in approval of WWII internment? (Anything since 9/11 probably qualifies as current-day sentiment) Also, is approval of internment more common in conservatives and older people?
(Side question: I'm assuming that most Americans are aware of WWII-era internment, regardless of whether they approve of it or not. Is that an accurate assumption?)
