What they did was wrong but it doesn't compare to the three years my father spent in a German POW camp untill his camp was liberated by American forces in 1945.
That was the other thing the old dude was trying to do.
First, the old dude wanted to show he's not a racist by decrying a racist act that took place before he was even born, where both the perpetrators and nearly all the victims have long been dead.
Second, the old dude was applying relativism--"we're just as bad as they are"--when in fact there are degrees of "badness." The
worst of the camps here in America into which a few tens of thousands of Japanese were sent were nothing compared with the
best of the camps in Europe and Asia into which millions, tens of millions, of others were sent.
It's really puerile, this constant primitive assertion that stepping on someone's toe is "just as bad as" killing someone.
