I never said that anything "excuses" the mistake of the Japanese Internet camps. I said that they should be acknowledged as the horrific mistake that it was, but ON BALANCE, he was a highly successful president, even with that black mark. That's not excusing it, it is treating history responsibly, and not trying weaponize it to advance an agenda.
Millions died fighting in WW2, or were gravely wounded, and many were draftees, like my father-in-law, who didn't want to go, but were forced to. Many, many American families made terrible involuntary sacrifices for the war, and unfortunately, the Japanese were forced to contribute to the war by their involuntary internment.
It wasn't the best situation, but considering the sacrifices that many Americans made, it wasn't the worst either. The Japanese internment camps weren't pleasant, but they weren't Auschwitz either. Families weren't being separated as they came off the trains, with some sent to work, and the rest to the gas chambers. I'm sure there were many Americans actually fighting on the front lines of the war that would have been happy to be in an interment camp back in America, rather than having German bullets whizzing by their heads in the Battle of the Bulge or Okinawa.
You are concerned with 100,000 that were wrongfully interned, instead of the millions of lives that were saved by the war, and the Japanese internment was considered a necessary step in the fast-moving preparations for the war. They worried about how deep any Japanese government influence might have reached, and they couldn't wait to find out when a spy sabotaged their war efforts, so they took a broad stroke to avoid it. Whether that decision was right or wrong, it was a different war, and a different time, and applying your contemporary attitudes to history, without properly considering the historical context, is lazy historical thinking.
Unions, Labor, Social Security, Employment Reforms, End of Child Labor, workplace Health/ Safety/ Environmental regulations, etc. have improved, and even saved, the lives of millions of people, including you and literally EVERYONE you know, and yet you would surrender all of it, because the president who did all that, made a mistake during the worst war in human history.
