The Constitution protected slavery. It was designed from the beginning to do so. Use whatever verbiage you think applies to it intending to be a permanent part of the US Constitution, but at least recognize that it was.
The Flag of Slavery was for "Four Score and Seven Years", the American flag.
What “nitpicking” have I committed?
The Constitution was written to protect FREEDOM not slavery.
A country which is based on Natural Law cannot accept slavery. The compromise was never intended to be permanent.
At the time of the Founding almost all the significant actors believed that slavery would die out if no more could be imported.
Then came the enormous wealth after the Cotton Gin and all of a suddenly it changed from a necessary Evil to a positive good.
