“In other words, just like everyone else, you have no real evidence of Japanese civilians spying for Japan during the war”
The fact that I, in my old age, cannot immediately put my finger on it, does not mean that it does not exist, nor that I have not seen it.
But what the hell, go ahead and close your mind. Nobody can stop you.
I've seen no such evidence, and you've produced none -- certainly not enough to justify internment of over 100,000 ethnic Japanese civilians.
In this regard, you might remember that the US government also interned civilians of German and Italian ancestry, but only, I repeat only when they had evidence of individual wrong-doing.
There was no effort to round up millions of ethnic Germans & Italians, just because they came from axis power countries.
Only Japanese received such special treatment.
That's why US courts eventually decided the FDR government did wrong in this matter.
