You've never actually read the Confederate Constitution, have you?
I have and done some decent research into it, have you?
CSA constitution:
Preamble-We, the people of the Confederate States, each state acting in its sovereign and independent character....invoking the favor and guidance of Almighty God
Article 1 section 2- Removes birthright citizenship and the ability to serve government of those who are "foreign born"
Article 1 section 6- But Congress may, by law, grant to the principal officer in each of the Executive Departments a seat upon the floor of either House, with the privilege of discussing any measures appertaining to his department.
Article 1 section 7- Line item veto is legal
Article 1 section 9- No bill of attainder, ex post facto law, or law denying or impairing the right of property in negro slaves shall be passed.
Article 4 section 2-
The citizens of each State shall be entitled to all the privileges and immunities of citizens in the several States; and shall have the right of transit and sojourn in any State of this Confederacy, with their slaves and other property; and the right of property in said slaves shall not be thereby impaired.
There is a lot more we could get into and we can even debate interpretations of articles but the CSA was not as you are implying a simple US- with a twist
