Everyone knows that the confederates were traitors. It is common knowledge.
I have to disagree. They seceded from the USA. The power to stop states from seceding was not given to Federal Government, therefore it should have been a power reserved for the States. Also the people at the time decided to heal the nation instead of resorting to that type of revenge.
I would say that any state does not have the ride to secede from the union as it is not in the constitution. The Constitution does not provide any way to dissolve the union. Now it can be amended. If an amendment gave the right to secede then they have a leg to stand on. As such they cannot do it, unless both sides agree to it. They can then amend the constitution to allow for it. The constitution is the supreme law of the land with the consent of the states.
The South literally shot themselves in the foot when they succeeded from the Union. This allowed Congress to abolish slavery with little opposition with the 13th amendment. Which lead to bringing them in compliance.
The argument that they are property goes against the general principles of the declaration of independence.
The interesting thing is that the original colonies broke from England and establish a country. They won the war and that allowed the US to become a country.
The South lost the war and were not allowed to become a separate country.
Yet a country that is based on slavery is problematic. If they manage to escape then why would they be returned. The issue become - are people property or are they people with free will.
