“After the Emancipation Proclamation, the north gained the moral high ground.”

The CSA had slaves. The USA had slaves too.

The CSA Constitution included protection of slavery. The USA Constitution included protection of slavery too.

The presidents of both the CSA and the USA took oaths to protect and defend their pro-slavery constitutions.

After the Emancipation Proclamation, one of those presidents added a slave state to his nation. Do you know which one?

Mr. Lucky: "West Virginia was added to the Union on June 20, 1863."

At the time of West Virginia's admission, it's constitution required gradual abolition, as was done in other northern States.
West Virginia officially abolished slavery on February 3, 1865, 10 months before ratification of the 13th Amendment.
