With a 1763 POD or later, make it so that there is a United States of America that breaks from Britain, but they are evil slavers with slavery engrained in all states.
"Wait but slavery makes no economic sense in the North"
Maybe it does, maybe it doesn't don't discuss it here. But the challenge is to make it ideologically baked in. That means if they aren't used for farmwork, have slaves in the North work as domestic servants for the rich (who are inherently unproductive to an agrarian).
So it means that people think slavery is "necessary" to avoid "the blacks controlling the legislature" or some other stupid racist reason you can make up.
The free blacks will be viewed as "exceptions" or something and no matter what they do, they can't be used as proof that slaves wouldn't act like wild animals when freed (or whatever justification you want to make up).
It must be so that up to 1870, there are 3 Americans supporting slavery for any reason other than "it's the status quo" (being a slave owner, racist reason, whatever) for every abolitionist (and yes, you can have lots of "I don't care").
Bonus points if the British manage to retain Ohio, a big point in the ARW and British end up using Indian states to keep American expansion limited to Tennessee, the equivalent of OTL Gulf states, "Mexico" or whatever breaks away from Spain if that isn't butterflied.
Bonus points if the British and Americans take more than 3 decades to reconcile the impending Slave Trade Act of 1807 (or whenever it comes in TTL, since there will be butterflies) and America's hunger for move slaves.
Bonus points if the British end up convincing much of Europe to put high "punishment" tariffs on America because of slavery and try to use that to Pressure America.
