I did.
Neither the word "Morrill" nor the word "tarriff" appears in any of the secession documents that I've seen, or that you quoted.
And all of the other Southern complaints, without exception, are minor issues, easily resolved by Congress's most powerful single voting block -- the South -- through negotiations with other Representatives.
Furthermore, the South had an absolute LOCK on the Senate -- nothing could pass the Senate over the South's objections.
There was simply no reason besides slavery for secession -- and the proof of that is: the South never seceded, or seriously threatened it, until the South feared slavery's future would be restricted, or even eliminated by the just-elected Republican president.
Every other "reason for secession" was added on afterwards.
They don't amount to a hill of beans, and they are not the real reason.
Slavery was the real reason.

I asked you to read carefully. The entire paragraph from Georgia was related to tariffs.

That’s odd considering the fact that South Carolina (the first state to secede) declared in their Secession Causes that the Republicans would take control of government in March, 1861. So maybe your “facts” are wrong (again). The following link shows that in the 37th Congress the Republicans and Unionists combined for a total of 34 votes. There were only 33 states at the time (Kansas was added a month later in Jan 1861).

Note that Mississippi also stated the Republicans had taken control of the government.
