I think you’re special. Sorry. You’re the one straining and trying hard to not understand the logic of four score and seven years later.
I don’t think you’re really this obtuse.
Gettysburg Address: 1863.
"Four Score and Seven years" = (4 x 20)+7, = 87 years.
1863 - 87 = 1776.
What happened in 1776?
A collection of Slave states declared Independence from a Union, (United Kingdom, Union of Crowns) Formed a confederacy, (Articles of Confederation) fought against the Union, (American war of Independence) The Union put forth an emancipation proclamation, (Lord Dunmore's proclamation) and the Confederacy's armies were led by a slave owning general from Virginia. (George Washington.)
So the year 1776 is celebrated because of *INDEPENDENCE*. The year 1776 had nothing to do with an oppressive Union government forcible subjugating people who wanted to be rid of it.
The Gettysburg address has completely flipped what happened in 1776 to make the oppressors (The Union) sound like the good guys instead of the bad guys.
This is what I mean when I say this is a con man bait and switch.
