That’s the thing, yes it was evil, but it was in a time when you judged men on social status, colour, and etc, not by personality, unless you were lucky enough to be in the position.
I’m not saying they should be forgiven, and their evils overlooked, but rather they should be judged by their evils and goods. George Washington led the people to freedom against the British Empire, he then brought the nation to be after it nearly fell apart(after the war ended) and yet people dislike based only on the evil of slavery.
If you went to war and protected thousands from death, you’d be judged on how many you killed rather than defended, and it’s infuriating.
Also not alt-right, not really into politics, I just dislike commies and nazis
