Which item listed is not true?
It's all ridiculous nonsense which begins by ignoring the fact that Confederates provoked war, started war, formally declared war, waged war in Union states and for four years refused to stop their war on any conditions better than Unconditional Surrender.
The US Constitution recognizes both foreign war and internal rebellion, allowing for suspension of certain liberties (i.e., habeas corpus) in such times.
So, what Lincoln did was perfectly constitutional and also later approved by Congress.
Remember the Constitution's definition of treason:
Of course our pro-Confederates say secessionists were not committing treason because they were then a different country.
But once the Confederacy started (Fort Sumter) and formally declared war on the United States (May 6, 1861) then any active pro-Confederates in Union states (i.e., Maryland, Missouri, Kentucky) were by definition guilty of treason.
That is why Lincoln had them arrested.
And that alone answers your items #1 through #12, except for #5 where the piece attempts to turn treason logic on its head declaring:
As for Lincoln's emancipation proclamation and confiscation acts, those were practiced during the Revolutionary War and thus were a normal part of a nation's actions during war or rebellion.
What does that leave, water torture against Union prisoners, #15?
That's a new one for me, perhaps somebody knows what this refers to?
