DO NOT EVER DOWNGRADE MY ANCESTORS WHO FOUGHT AGAINST THE NORTH'S ILLEGAL INVASION OF THE SOUTH.
You can thank the north for keeping the south from creating a hellhole of a country that would make South Africa look like a good place to live.
But it's all right for you to denegrate my ancestors by labeling their cause an 'illegal invasion'?
Your ancestors were engaged in armed rebellion against the United States. Their leadership launched the rebellion to protect their institution of slavery from what they saw as threats to its expansion by the Republican administration. They started that rebellion by firing on the federal troops in Fort Sumter. And they lost. If pointing out any of that is downgrading your ancestors then so be it.
