This was someone else's fault.
Slavery was France's Original Sin.
It was already well established in Virginia and Georgia. France had it, as well as Spain, though.
Google Admiral John Hawkins. He was important in the reign of Elizabeth the First and began the slave trade from Africa to the West Indies.
Slavery existed in the Thirteen Colonies.
Moreover, before the ACTUAL American revolution against Britain, the British loyalists were also among slave owners.
The attempt by the Left to make slavery into a Democrat talking point has been insidious and wholly unfounded. One finds easily:
"During the Civil War, the Republican Party was the anti-slavery party of the North, led by President Lincoln, while the Democratic Party was divided, with its Southern wing supporting secession and slavery, and its Northern wing opposing Republican war policies. Republicans championed a strong federal government, while Democrats largely favored states' rights."
For any and all who would find the following graphics somehow offensive, this graphic of a Democrat campaign ad in the Civil War era is found in the "America's Black Holocaust Museum" website.

Your continuous efforts to absolve the United States from any complicity in slavery reminds me of the people who for decades maintained the Rosenbergs were innocent.
After the opening of the Soviet files in which it was revealed that "Yes, the Rosenbergs were spies", even the most hardcore advocates finally admitted the truth.
I don't think you are susceptible to any such solid proof regarding your desire to separate the US from slavery.
I can't speak for others, but to me it comes across as a little obsessive.
But good luck to you.
We’d already decided to go back on our founding statement and keep slavery by the time the Louisiana Purchase happened. We didn’t create it, but the western world was already starting to consider it a problem. And we had the audacity to declare it was a self evident truth that all men are created equal. Except in some states. Whining about who started what when is just playing the distraction game. We knew it was wrong, but we did it anyway.
Slavery goes back thousands of years a must read book (Lies My Liberal Teacher Told Me) has the facts the liberals don’t want known it’s bad for their agenda and power.

Slavery has been practiced since the beginning of civilization. Christian nations ended it.
Slavery was extremely widespread historically, but pretending there was no slavery in the colonies and US before the Louisiana Purchase is delusional.
Nonsense. Slavery was also well established in the British colonies and continued after independence. It is interesting to read the “Code Noir” and note certain key differences regarding slave laws in French Catholic territory and the U.S.
Not that all slave owners held to the code.
I don’t think anyone argues that the U.S. originated the practice but it certainly was not established by the French either.
The Louisiana Purchase did not include the slave owning states of Arkansas, Alabama, Mississippi, Georgia, Florida, South Carolina, North Carolina or Tennessee, so its overall impact on slavery in the United States was not THE MAJOR factor, regardless of the slavery inherited in the territory bought from France.
It is not the fault of the Colonies that they have among them so many of these unhappy people. They have made laws to prohibit the importation of them; but these laws have always had a negative put upon them here, because of their tendency to hurt our Negro trade. - Richard Price, "Observations on the Nature of Civil Liberty, the Principles of Government, and the Justice and Policy of the War with America" page 42
To those of you willing to listen, this is actionable history.
True it's written from the British and not French perspective but the end result really is not all that different.
The colony is the parent country's responsibility and the parent country's guilt and in this instance, Louisiana was of France. That is where the pre-purchase guilt resides.
Don’t see many if any stories if white people taken into slavery it doesn’t fit the agenda of the evil white people.
France abolished slavery in 1794 and Napoleon reintroduced it in 1802. The next year he sold us the Louisiana territory. If we wanted to make it all free territory we could have. We would have had to make terms with the slaveholders, I suppose, but we weren’t under any obligation to France to maintain an institution that they had only just reintroduced.
