Uncommon Commentary #514: UC #513 Follow-Up

It’s also noteworthy that President Lincoln in the Gettysburg address made no overt reference to slavery, possibly alluding to it once when he expressed anticipation of “a new birth of freedom”, even though he had issued the Emancipation Proclamation a year earlier.  Had he abandoned his presentation of the Union’s war upon the Confederacy, which actually was a hypocritical effort to quell the secession of those 11 Southern States, as a crusade against slavery? (Yes, hypocritical.  It’s only logical that those 11, or any other States, had a right to secede from a country which had itself been founded by a unilateral declaration of independence from the Kingdom of Great Britain.  What the Union ought to have done was to simply allow the Confederate States to leave the Union in peace.)
