The Civil War ended the Southern Slave Empire in 1865, but unfortunately post Civil War Reconstruction failed, since it should been extended at least another 150 years, in your case:)
Nazism, as POPULARIZED by one Hitler, has been around far longer that 1939. A belief in a pure, master or superior race, a belief in nationalism, and attempts to purify the country by eradicating allegedly inferior races. Most European/American people in the 1800's shared this position, and numerous leaders believed in the superiority of the white race, and many Union leaders went so far as to practice ethnic cleansing/genocide during and after the War of Northern Aggression.
A certain American President, one Abraham Lincoln spoke often about the superiority of the white race, of his dream for a lily-white country, and repeatedly attempted to have blacks leave the country. After the war, for decades ethnic cleansing was praticed in the West, and Indians were slaughtered for the crime of being a red-man.
As evidenced by numerous posters on your side, there are posters here that share Sherman's view that ALL things Southern, men women and children, should have been exterminated.

Slavery did NOT end in America with end end of the war, it ended in the YANKEE states with the passage of the 13th Amendment MONTHS after the end of the war. Slavery exists TODAY - it has NOT been ended.
PS. Other than a difference on this issue, most of us - including me - are very CONSERVATIVE, very close to your ideology. To me Ronald Wilson Reagan was the greatest President of my lifetime.
But, to be fair, it should be noted that the Northern slave empire was subsequently ended by the 13th Amendment.
Brazil ended slavery by decree of the Emperor. There was no great change in the status of the former slaves in Brazil, either.
The German Nazis were defeated by the allies. Naziism was not defeated, and in fact still exists today.
The South was defeated in the WBTS. Slavery did not end with the defeat of the South, ended in America after the 13th was passed, but slavery has not been ended and in fact still exists today.
The Soviets were defeated in an economic contest. Communism was not ended with the collapse of the Eastern block and the Soviet Empire, and still exists today.
Fascism was not defeated with the end of the Germans. Fascism was not defeated with the end of the Japanese imperialists. Fascism was not defeated with the toppling of Saddam Hussein. Fascism is alive and well today.
