"And you don't get to call it "abolished" until it is actually gone!"
and
"The United States abolished slavery before Britain did. Some 35 years prior. All hail the United States for being first.
Sounds reasonable to me."
This level of consistency was not expected. So then the error generally is mine, not yours. Things like this could have been stated plainly a lot sooner. So that its said here: I do think Britain abolished slavery in 1833. They deserve credit, the did it right.
I'll await any and all replies and come back tomorrow.
To be pedantic about it, Britain initiated the abolishment of slavery in 1833. They didn't complete it until 1907.
Portions of the US initiated the abolishment of slavery in 1780, but the entire nation did not completely abolish slavery until 1866.
