Lincoln was not an “early President”. He wasn’t even born until 1809.
Lincoln was also trying to explain to his base why seceding from the Union was the right thing to do in 1776, but nowadays seceding from the Union is terrible.

The colonies, however, did not secede from Great Britain, because they were never part of Great Britain. They were colonies. The situation in 1860 was quite different.
Nope.
The colonies were part of the British empire. The wealthy WASP male folks preferred not to remain, so they seceded.
Similarly, the wealthy WASP male folks in the Confederacy decided to secede from the other states. They didn't try to take over power in northern states any more than the founding fathers tried to take power in England.
Like the British, the northern elite launched a war to force the Confederate states to submit. Unlike the British, they were not fighting any other wars and didn't have to cross an ocean to project their power. So they won and British didn't.
