I didn't say it was subject to Congressional approval. I said that they have to follow Article IV in doing this act.
Congress did not think it did, but you do. So, continuing with this >>> "I never said secession was prohibited, I said the Congress gets to set the rules for proof of secession" <<< is proof of your wish to continue deception.
What deception? Article IV is clear and it says Congress decides how acts are proven.
It seems as if you believe that repetition proves truth, which of course does not.
No, repetition is necessary when the opposition repeats their faulty position though.
No one has asserted that Article 4 controls secessionist movements.
I don't care what anyone else has asserted. The Constitution was to be read by the people and reading it for ourselves, we can see that it clearly says the Congress may prescribe laws for states to prove their acts.
If it did, Buchanan, Black, Seward, and Lincoln would have seized the moment.
Lincoln did, didn't he? Did he ever call the South's secession a legal secession?
