Lincoln was never pro-secession. Lincoln did uphold the principles of revolution as put forth in the Declaration of Independence.
Same thing in practice Colonel Kangaroo. What is the difference between “the principles of revolution as put forth in the Declaration of Independence.” and that of secession?
I remind you that all of the Southern States published their own Declaration of Independence, in all cases the people of the states voted to leave the union which is more then what all the 13 states did in 1776.
If they were not “in revolution” in the exact same sense of our forefathers in the “Declaration of Independence” secession, the then term “revolution” as you and Lincoln have chosen to uses it here is utterly meaningless.
Yes play all the word games you want but as Lincoln used the term revolution its only possible meaning is to include secession. Either way the Southern States did the paper work even better and more completely then the 13 colony did to qualify as “a revolution” in exactly the same sense.
