Abolishing the slave trade in 1807 you say? That would be quite interesting to American sailors forced into servitude on British ships by impressment until we kicked their ass in 1812.
I must have missed the part were men were bought and sold under impressment. Perhaps you’d be good enough to show us such an example.
Calling impressment “slavery” makes as much sense as calling our military draft slavery. You didn’t burn your Impressment Card, did you?
In fact, Mr. Madison's War (which considering his ties to Jefferson might classify it as one of our several Democrat inspired and ill considered wars) almost undid us. The Brits finally concluded that peace and a gradual reconciliation was better than more wars that they could at that time not really lose, but neither outright win, with their rambunctious and increasingly powerful cousins.
