You should read what the British dummies over at The Guardian say about the Constitution - which they think was written only to defend slavery. Stupidity, cupidity is worldwide!
Oh the irony. Suggestion: if you're wanna be a playa, you might consider coming prepared. The arguments the British make about American independence and slavery are exactly the same associations made with respect to the Confederacy. But, because I'm a nice guy, I usually provide some informational links to help potential allies up their rhetorical game so to say.
1772 - after decades of abolitionist agitation within the church/society of England, the High court decides that slavery has no common law support. Ergo, the slaves are freed. https://en.wikipedia.org/wiki/Somerset_v_Stewart
1776 - US declares independence. All 13 states still preserve slavery as a core feature within their respective charters. PA is the first 'state' in 1780 to begin introducing abolitionist legislation https://en.wikipedia.org/wiki/Slave_states_and_free_states
You might know that the earliest divide in the US - in fact, the one that eventually manifested in the first Civil war - wasn't really about slavery per se, but the political legacy each region experienced from the original founding of the two key colonies: Plymouth (New England) and London (Virginia). As is quite evident, the reason certain northern states were the earliest to abolish slavery were they where the ones in closest alliance/influence from England and English intellectual thought. Virginia was associated with the French and a more rigid, stratified society.
Anyway, this is the thinking behind the arguments made by the Guardian, et al. They make a very good point: how come Washington & Jefferson, the two richest men in N America and both slave holders are heroes gaining independence, while those who led the South under exact same rationale, are somehow just historical footnotes?
Among the MSM worldwide Ignorance, Stupidity, and Cupidity is tolerable.
Among leaders of Nations, inexcusable.
The Rights of Man as a concept from Great Britan is the grandather of our Constitution, which begs the question : When did the British Empire finally outlaw slavery?
Hmmmm?
