...FDR knew in advance the Japanese were going to attack the U.S., and that's specifically why he instituted the Oil Embargo. He was a huge fan of Stalin, the biggest mass murderer in European history. He brought Marxism to the United States. He tried to destroy the judicial branch of government. (See: 1848 Manifesto)
He was charismatic, and he was elected four times. But for all of his progressive views, he was still very anti-black in his actions, in a time where he could have sparked the civil rights movement 30 years ahead of time.
In closing, I could say the same to you. How dare you compare FDR to Ronnie Raygun.
FDR and Mao are in Civ 4. If FDR is a bit of a strong thing to say, then, uh... Elizabeth, who enslaved millions and attempted to exterminate entire Irish sects is in the game
