You can’t possibly be so ignorant as to hold to the statement that “America invented Abolitionism”
It should not take you long to discover the facts contradicting your belief.
There are no transatlantic countries who were doing abolitionism earlier than we were. Our abolitionist movement organizations are as old as the 1770s and we have one-off abolitionist persons going back into the 1600s.
The very first transatlantic abolitionist tract written anywhere, ever, was by an American. Ever. Period. The very first. The "oldest" in that sense. It was in 1700, "The Selling of Joseph".
No other country can come close to posting numbers like that. If you require details I will be happy to drown and overwhelm this thread with it.
America did that. We own it. Period.
