Let's make this clear.
THE USA BEFORE WWII AND DURING WWII WAS WAY WORSE THAN THE NAZIS EVER WERE.
This is absolutely clear from the historical record.
Even if Hitler DID kill 6 million jews (which is entirely fiction), even if he was a totalitarian dictator (he was not), it was still nothing compared to what FDR actually did.
If you don't know this, you haven't paid attention to history.
