Words have meaning. I said the US never freed slaves in the US until well after the war ended, December 1865. I am correct. You are the one that has a problem with it.
Well, then you either don't know what you're saying, or you're being very deceptive, I suspect the former.
The fact is that every Northern state abolished slavery many years before 1860.
In 1787 Congress abolished slavery in the Northwest Territories and in 1820 in all US territories north of the Mason Dixon line.
In April 1862 Congress abolished slavery in Washington, DC, and in June 1862 Congress abolished all slavery in all US territories.
So, by 1863, the only lawful slavery was in five Border Union States, and of those three abolished slavery before the war's end and the remaining two -- Delaware & Kentucky -- had very few slaves left to free.
So your problem with the truth is what, exactly?
