As bad as it was to incarcerate American citizens simply becuase of their race during WW 2, it would be an egregious error to say that it was morally the same as the Holocaust. No not all sins are equal, not even close.
Well, true. Both were reliant on race/culture/faith. As for the holocaust, I have NEVER gotten an answer as to whether Judaism is a faith and/or a culture. Doesn't really matter, I suppose.
One incarcerated; one tortured and killed. They would seem to me to be MILES apart.
