That is an interesting comment; about the “Slavers” I mean.
Now, let's name the American slave states that voted to enshrine slavery into the United States constitution: New York, New Jersey, New Hampshire, Connecticut, Pennsylvania, Massachusetts, Rhode Island, Delaware, and Maryland.
Oh yes - Virginia, North and South Carolina, and Georgia were slave states too.
Now a question: did the Union slave state of Delaware send soldiers to fight the Confederate slave state of Virginia in order to end slavery or to protect slavery?
Did the Union slave state of Maryland send soldiers to fight the Confederate slave state of North Carolina in order to end slavery or to protect slavery?
Did the Union slave state of Kentucky . . . and so forth and so on.
Did the Union slave state of Maryland send soldiers to fight the Confederate slave state of North Carolina in order to end slavery or to protect slavery?

Maryland fought both ways. Those West of the Chesapeake Bay fought with Pennsylvania for the North. Those on the Eastern Shore of Maryland fought with the Army of Northern Virginia, therefor for the South.
Please even the slavers among the Founders believe it to be an evil and it became even more so after the Cotton Gin made cotton growing extremely profit. Ironic that the wealth of the South was due to that Yankee, Eli Whitney.
BTW the word “slavery” is not in the Constitution much less “enshrined” in it.
The tolerance of slavery was the compromise which allowed the formation of the Union. The Northern states basically ignored it, not affecting by it much.
Lincoln fought the war because of outrages to federal property and to preserve the Union. When the situation was ripe he made slavery the next issue.
