There is a reason that slavery was enshrined - err, I mean included - in the U.S. constitution and it's not happenstance.
Slavery is included in the U.S. constitution because the states of New York, New Jersey, New Hampshire, Connecticut, Massachusetts, Pennsylvania, Delaware, Maryland, and Rhode Island and Providence Plantations voted to include it.
Oh yes, Virginia, North and South Carolina, and Georgia also voted to include it.
There had to be a compromise to keep the 13 colonies together as one country.
So what?
Do you want to bring back slavery?
